I had all kinds of problems with my Onan, it would run fine until it had run for a while, and was shut off. When trying to restart it would throw a code 34, and would have to get completely cold before it would restart. Turned out to be a weak fuel pump. Replaced fuel pump and it always starts now. Replaced fuel filters, fuel line, module. Good luck it can be a real pain.
