After starting my car it performs perfect for 3 minutes then looses power. But if turned off then back on its fine for another 3 minutes. Had a diagnostic done and 8 problems showed up. Failed fuel injector for all four cylinders, failed Air injector pump relay, failed air solenoid valve, failed coolant temp sensor, failed leak detection pump. The spark plugs are heavily coated with a white powder as well. What component could cause all this to happen at once?

codes never identify bad parts, just failed systems
