FR3 Onan Generator - won't keep running Have you changed the oil in the Onan yet? Mine started to crap out like that at 17 hours. They told me to keep the door open and run it to 20 hours and then change the oil. It also could be fuel sloshing around while on the road and the fuel hose not picking up. Not sure how the FR3's tanks are setup. In our toy hauler it will only let you pull to about a third of the tank. The theory I guess they had was they didn't want the generator to cause you to run out of fuel.



Overheating could very well be the culprit though. Is there a vent sound your generator anywhere that could be opened? __________________
