OP here. Finally back with the solution.
I decided it was a faulty fuel pump. I bought a new fuel pump, fuel filter and air filter. I also bought an ON/OFF switch so I can kill the generator by turning off the fuel pump.
I opened it up. Got all of the stuff out of the way so I could get to the fuel pump. I had ONE SCREW to remove and the job would be over. I COULD NOT get that screw loose. I sprayed it with penetrating lubricant for 3 days. I used a ratchet for torque, and even hit the handle with a hammer for shock. I bought an impact driver. No luck.
Finally, I gave up and put it all back together. I took it to Cummins/ONAN. It took them 3 days to get it back to me. The paperwork that I got when picking it up said that the screw holding the fuel pump in was rusted in and had to be cut out. They drilled out the hole and put in a nut and bolt to hold the new one.
They would not use the hardware I had bought, so I have spares, and no ON/OFF switch still.
Sigh.
