Have you checked your coolant level? Mine would do something similar and what was happening was it would get hot and shut down. I had a very slow leak at a hose that I had not caught and over time I lost enough coolant to cause the overheating.

What is the level of your fuel tank? If the tank has a significant amount of contaminate in it it could be drawing some fuel(partially clogging the filter) through until it can not get enough to keep running. When motor is first started the fuel pump will fill the fuel system up but will run until it cannot keep up.

Sounds like a fuel issue, on a coach that old you may have deteriorated fuel lines sucking air, bad elec fuel pump loose fittings. These kind of problems on older M/Hs can make you pull your hair out and flatten you wallet as well. Good luck

Another vote for checking the coolant level, happened to me last year. Might also see what other safety devices shut down the generator and check there.

Same thing, a full service, oil, coolant, fuel filter, air filter, oil filter. Fixed the problem for me.
I wish they put a engine temp gauge on these things.

The fact that the genny will run for a half hour before stopping IMO points away from fuel being the problem. Half an hour sounds a little long run time for overheating problems but could well be the problem. Most gennys have a low oil shut off and tho stated it was serviced does it have proper oil level. Oil level sensor could be getting flaky
