2000, Onan 5000 gas genset, runs then quits

I was told by onan rep that you never know when the pump will go out.I bought a new pump and filter from amazon took 1/2 hr to replace.works great.the pump was 45.00 so I ordered a second one and carry a spair and filter and air cleaner and oil filter.

Same problem was the fuel pump for me. Easy replacement from NAPA or Amazon. Did the filters and hoses while I was at it.

Thanks for all the help. I have reached the end of my skills. Will get the RV shop to diagnose.
Again, thanks

Chuck

Thus should have your answer.

Thanks for all the replies.
I have checked the oil, we are at 6feet above sea level, the adjustment is for that.
Keep the help coming.

Thanks

something on the unit is causing your fuel pump to not get power, when you hold down the start button you bypass the built-in protections that shut off the power to the fuel pump. oil level is the most common one.

At what altitude are you camping ? Most have a a adjustment by the carb.

Had a similar issue with my Onan 5500, replaced both fuel filters and the fuel pump, that was 6 months ago. I exercise it monthly on full load, hasn't quit yet.

Fuel filter or fuel pump.
