First order is change fuel filters.

How long does it run before shutting off? Is the shutdown quick or does the engine stumble?  What does the fuel shut off do in conjunction with the shutdown?

I don't believe it is an engine issue, it starts and runs up to governor, then within a couple seconds it slows to an idle speed for about 5 seconds, then shuts down. Engine sounds perfect the whole time. Zero AC voltage output though.
