Onan Marquis 5000 quits after a while?
I have a BGM series Onan Marquis 5000 which fires right up. After about 20 minutes it just randomly dies. Then it won't start for 10 minutes or so then will fire up again. Sounds weird, but it seem...

Mine acted the same way, changed the air filter and it started running like new. We run ours while on the road to run roof air. They pick up a lot of dust hanging on the back end . Ours was plugged with only 5500 miles on MH. Now carry a air filter and fuel filter. Good luck!!
