Generator stalls

It starts up beautifully, runs for a few minutes then stalls. After it stalls it will restart beautifully and run for a few more minutes then stall. I have adjusted the oil and antifreeze levels and unplugged the remote switch to rule out the remote switch.
Was thinking the fuel filter might be clogged but a little voice in my brain says that if this was the case it might not start so easily.( but the fuel filter might be the issue) Oh after it stalls it flashes once repeatedly and after i touch the off position it flashes 3 times incrementally. It stalls with or without a load.

Its a onan diesel...

Thoughts?

    Likely fuel related. How full is the tank? The generator will only draw the tank down to about 1/4 so make sure it's above that.
    The engine doesn't draw much fuel at idle and lightly loaded; a clogged filter would only show itself when a load is put on the generator. Or, you could have an air leak somewhere in the fuel system including a loose filter. Have you tried tightening it?
    The flashing light is giving you a fault code. Have you looked it up in the manual?
