Have you ran a cylinder test? Loosen the spark plug wires , then with engine idling, remove one wire at a time. It engine dies when wire is removed, the opposite cylinder is not firing. Check it for spark and compression. You may have an engine that is running on one cylinder! These engines run well with just one cylinder firing, but have no power when under load. Try that and we can continue from here. Thanks.
