So, what happened with this Onan? Did it ever get resolved what the problem was? I have the same Onan issue, and haven't found the culprit yet. New plugs, wires, coil, points, condenser, fuel pump, I tried a rebuilt carburetor - same result. I've tried a separate fuel container. Tried it suspended above the carb and directly feeding it. Cleaned the carbon off of the pistons and heads. When cold, it starts right up and after 5-10 minutes, it runs rough, with no load.
