Check the oil, do you have a auto transfer switch?

If the oil is a tad bit low it will trip the low oil safety switch, it's fine when starting but when the engine get running the oil is lower in the crankcase and then shutsdown.

What sort of message are they sending by naming their products Onan? Repent sinners!

That was my first hunch oil ok and oil shutdown relay is good. Did get my hands on a schematic at lunch. Looks like if the relay board gets a bad signal from the generator it will shut down. Going to look at brushes on generator.

What type of fuel? If the transfer switch relay is bad you could have the problem that you are experiencing.

I must add aside from tinkering with boat generators my knowledge is very limited.
