Have you ran a cylinder test? Loosen the spark plug wires, and with it idling remove one wire at a time. Engine should continue to run. If engine dies when one wire is removed, the opposite cylinder is not firing.

Engine can run really well on just one cylinder, but can cause surging and lack of power. If it does have dead cylinder, check the spark, and then check the valves.
