4000 onan.Will run great while parked. Driving it cuts off about 20 minutes into trip. It’s 42 degrees, so I don’t think it’s heat. However I have replaced carb, fuel pump, air filter, fuel lines are wrapped in heat shield, fuel pump is wrapped in heat shield, inline fuel pump was installed by fuel tank.I took outer rv door, not generator cover off.That didn’t help. Any is help appreciated.
Hi and welcome. You are posting a question as a response in a thread that's 7 years old. You may find it beneficial to ask your question in a new post as it's likely to get more answers than being buried in a very old thread.
That said, have you checked your wiring? A loose ground could cause your genset to stop running - not moving keeps it connected while driving it may jar it loose. Also, is it throwing a code? Gensets require constant power from the batteries to keep the fuel solenoid open.
