The Onan on my 41 would run for awhile and then die. It could be 5 minutes or 5 hours. Usually it would start back up but every once in awhile it would take a bit to restart and blow a fuse on the starting circuit.
It started getting worse so I set there one day and watched it run and die numerous times. Each time it would start to stumble and act like it was running out of fuel. Replaced the fuel pump and all problems went away. Even if they look perfect, they can still be bad.
