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...

I think it's better now. It was almost 'rattling' or knocking kinda like it does when you turn it off (just as you turn it off and it sputters, it does kind of a knock as it dies). It was doing that like it was at too low of a rpm. The owner told me that the generator was serviced last year. I have done a new fuel filter before I posted this problem. Today I found the air filter to be dirty, as well as a little foam piece wrapped around the fuel filter.
Even though I put fuel cleaner through the tank, while I had the air filter off I ran carb cleaner through the butterfly on the carb.
It seems to run better and hasn't stalled.
What's weird is that the air filter seemed to make a difference, and even to test that I covered the entire air intake with my hand and it wouldn't die. What the hell? lol
