I have a Onan 5500 marquee gold. Run fine for 20 minutes and dies. Oil level up, replaced fuel filter under carb and changed air filter. Checked to see if pumping fuel and it is. Still won't run continuously. What next?

You need to check the fault code, and see what fault is shutting the unit down.You most likely have a bad fuel pump, but it may be ignition related.

I backed out of the site when I found there was a charge and was still charged. Response was ok. Was going to checked the fuel pump anyway because code was 36. Was checking internet to see if others had same problem and ended up being charged.
