can anyone help me with my Onan 6k? It ran perfectly 2 years ago. It slowly starting running rough. Now it will start and run on a low RPM for maybe 5 minutes. After that it becomes really rough and eventually quits. I have done the following and nothing has changed. It still acts the same as it did.

replaced spark plugs, fuel pump, converted to Bovee's electronic ignition, rebuilt carburetor. I had previously installed Dinosaur board.
I notice that the front cylinder seems to have a stronger spark than the rear.
My next plan is to change plug wires and coil.
I am running out of ideas. (and new parts to throw at it)
Has anyone had a similar problem and can share your experience with me?
