My Onan Marquis Gold 7000 (gas) starts and runs for just a few minutes and then shuts off. It is putting out AC power and all fluid levels are OK. Engine runs smooth and without warning shuts down. It goes from a minute to about 5 minutes before it shuts off? It has been serviced recently and runs smoothly when it is running. Any ideas?

Check the fuel lines for cracks inside that pull shut with flow. Tjis starves the engine.

Does the switch flash when it shuts down. If so it is a code. If it was recently serviced it could be an air bubble in the radiator system causing it to overheat. If lack of fuel it might tend to die roughly versus like getting cut off.
