Onan 5500 Generator in Holiday Rambler 1998 Endeavor

Generator runs sometimes and then shuts off.
Replaced with new:
Spark plugs, oil change, oil filter, air filter. "still no run"
Replaced:
New carburetor, New fuel pump, New fuel filter, No gas line hose from carburetor to fuel pump.
"still no luck"
The in line 10 amp fuse above stop/start switch is okay. The 20 amp
two blade fuse by breakers is okay.
I help "stop button" in for 15 seconds to prime Gen. and then hit start button and it started and ran for 60-90 seconds and then started getting rough and shut off and would not start.
I ordered new 5 blade relay plug under air intake to see if that is problem.
Are there any other in line fuses that could be problem
Any suggestions would be greatly appreciated.
  • thanks, I will check for spark.
    How do I get a manual for this Model (1997)
  • Stop throwing money at it!
    Have you checked for spark at the spark plugs?
    Possible bad coil or plug wires.
    Does it make any attempt to fire? Any back firing?
  • You need to make some friends at a local small engine shop. Onan engines are all over the place and they will probably have seen this before.
