1. An engine system comprising:a single engine having an output shaft, first power producing member and a second power producing member, wherein both power producing members produce power to drive the output shaft; a first set of systems serving the first power producing member; a second set of systems serving the second power producing member, wherein the second set of systems is separate from the first set of systems and comprise systems of the same type as the first set of systems; a first fuel system including a first fuel source providing fuel to the first power producing member and not the second power producing member; and a second fuel system including a second fuel source separate from the first fuel source providing fuel to the second power producing member and not to the first power producing member, wherein the engine is operational when one of said fuel systems shuts down and no fuel is provided to one of said first and second power producing members. 2. The system according to claim 1 wherein the first set of systems do not serve the second power producing member and wherein the second set of systems do not serve the first power producing member.3. The system as recited in claim 1 wherein the engine is selected from the group of engines consisting of Otto cycle, diesel and rotary engines and wherein the power producing members are selected from the group of power producing members consisting of pistons and rotors.4. The system as recited in claim 1 wherein the first and second set of systems each comprise systems selected from the group of systems consisting of air handling systems, sensor systems, cooling systems and control systems.5. The system as recited in claim 4 wherein the air handling systems each comprise at least one of a turbocharger and supercharger, wherein the sensor systems each comprise a temperature sensor, and wherein the cooling systems each comprise a cooler.6. The system as recited in claim 1 wherein the engine is operational when said one of said fuel systems shuts down and one system of said sets of subsystems is fully or partially inoperative.7. The system as recited in claim 1 further comprising a computer controlling the operation of each fuel system and each system of said first and second sets of systems.8. The system as recited in claim 7 wherein the computer monitors the function of each fuel system and each system of said first and second sets of systems and controls the operation of each of said systems in response to the monitored functions.9. An engine system comprising:a single engine having an output shaft, first power producing member and a second power producing member, wherein both power producing members produce power to drive the output shaft; a first set of systems serving the first power producing member but not the second power producing member; and a second set of systems serving the second power producing member but not the first power producing member, wherein the second set of systems is separate from the first set of systems and comprise systems of the same type as the first set of systems, wherein said engine is operational when two systems of said first and second set of systems are inoperative. 10. The system as recited in claim 9 wherein the engine is operational when more than two systems of said sets of systems are fully or partially inoperative.11. The system as recited in claim 9 wherein the engine is selected from the group of engines consisting of Otto cycle, diesel and rotary engines and wherein the power producing members are selected from the group of power producing members consisting of pistons and rotors.12. The system as recited in claim 9 wherein the first and second set of systems each comprise systems selected from the group of systems consisting of fuel systems, air handling systems, sensor systems, cooling systems and control systems.13. The system as recited in claim 12 wherein the fuel systems each comprise a fuel pump, wherein the air handling systems each comprise at least one of a turbocharger and supercharger, wherein the sensor systems each comprise a temperature sensor, and wherein the cooling systems each comprise a cooler.14. The system as recited in claim 9 further comprising a computer controlling the operation of each system of said first and second sets of systems.15. The system as recited in claim 14 wherein the computer monitors the output of each fuel system and each system of said first and second sets of systems and controls the operation of each of said systems in response to the monitored outputs.16. The system as recited in claim 15 wherein the computer shuts down the operation of one or more systems in one of said first and second sets of systems in response to the monitored outputs of one or more systems in said one of said first and second sets of systems.17. The system as recited in claim 15 wherein the computer reduces the operation of one or more systems in one of said first and second sets of systems in response to the monitored outputs of one or more systems in said one of said first and second sets of systems.18. The system as recited in claim 9 wherein said engine is operational when the two systems of said first and second set of systems are inoperative and wherein said two systems are different systems from the same set of systems.19. The system as recited in claim 9 wherein said engine is operational when the two systems of said first and second set of systems are inoperative and wherein one system of said two sets of systems is from the first set of systems and the other of said two systems is from the second set of systems.20. The system as recited in claim 19 wherein said one of said two sets of systems is a different system from said other system of said two sets of systems.21. An engine system comprising:a single engine having an output shaft, and at least two power producing members, wherein said power producing members produce power to drive the output shaft; and at least two sets of systems, wherein each set of systems serves only one of the power producing members, wherein each set of systems serves a different power producing member, and wherein each set of systems is separate from the other set of systems, and wherein said engine is operational when two systems of said at least two sets of systems are inoperative.
