Onan hot hot hot
I had trouble with my gennie dying for years. I spent a couple thousand at CW, they called in onan twice, kept it for many months. I pulled the fuel pump and replaced it. Runs great. I drove 200 miles...

But we are still either vapor locking or control board is getting too hot and shutting off fuel flow.
What I did to ensure it wasn't the control board. I ran a hot wire from positive to the fuel pump directly. The control board no longer had any power to start or stop the fuel pump. I had the same failure still so I know its not the control board.
When doing this test you have to have a fuse inline, and I put it outside the gen box so I could grab the fuse and pull it quickly to kill the pump. You must be judicious to quickly kill the pump when the generator dies or when you turn it off.
Personally the fuel pump seems to be in a very bad location, it gets no airflow and remains really freaking hot. I might add a 12v muffin fan to get some air to it.
