Is there an inline fuel filter besides the Onan filter

2015 Forest River work and play. It has a fuel station and an Onan mounted on the nose. Yesterday it was running fine then quit, it has 25hrs on generator, previous owner used it very little.
So i checked the filter behind the fuel pump and it was clear, the pump ran constantly and was not picking up fuel. i used a small hose into a fuel can to eliminate the long fuel line from the rear of the trailer and still nothing.
This morning it started and i ran it 3 hours underload. Since I had the unit, about 6 weeks now I have put 10 hrs on generator.

My thoughts are a clogged fuel filter someplace else. electric fuel pumps don't repair themselves overnite. With the fuel station and pump nozzle on the rear, is there another fuel filter somewhere?
Reminds me of the urban legends about a plastic bag in the fuel tank sucking up to the line and clogging it....

  • My first guess would be check the oil level. I'm betting that generator has a low oil cut-off. As oil gets moved up into the motor the level drops enough to shut it down. After it sits the oil trickles back down allowing it to run until enough gets back up into the motor.
    Along those same lines, is the unit level?

    Or the coke bottle inside the door post on a car with a note that said "Annoying, wasn't it?"
