I really appreciate the help!Re: Onan generator dies like its out of fuel then runs fine?Oil is fine, I'll try the fuel filterOnan generator dies like its out of fuel then runs fine?Hi I have an Onan marquis gold 5500 generator in my trailer. I had it out a month ago at 5500ft elevation. I was running it and it choked out and died like it ran out of fuel. Got home, 5250 ft elevation, gased up and it ran fine. I took it out this weekend camping at 8570ft elevation and it choked and died like it was out of fuel, I got under and looked and had over 1/3 a tank left. I started it up a while later and it ran for 15-20 minutes and died the same way. We came home and for kicks I fired it up and it ran for over an hour just fine so I shut it off. Any suggestions as to why it is doing this to me ??? :(
