Many things can cause the symptoms you are describing. Need to try and narrow it down. May be a fuel delivery problem, or electrical ignition problem. I would suspect an ignition problem. Can you check the spark when the problem is occurring?

sounds like coil or box getting hot and shutting down. Do as Pnwboat suggested and check spark when it acts up and post the results
