The 5 amp fuse protects just about everything electrical in the Onan except the starter If it run OK with the prime activated that means the fuel pump is OK NEVER use a fuse greater than 5 amp or you can / will easily burn the land patterns on the board

Some Onans have a fuel solenoid. Remove, soak / clean it. A cracked hose on the input side of the pump could leak and cause this The hose is under negative pressure and will not leak gas. It will leak air into it.

I would run the onan until it quits and them immediately remove the carb bowl. If there is no gas in it, you will know you have a fuel delivery problem.
