    I'm going to put money on fuel delivery being the issue. What is going on in the filter(s)? If it was an ignition problem it would break down and kill the engine for good. I think you are getting sporadic blockages in the jets. Next time it starts running like a 3 legged donkey, pull the air filter off it, start the engine and try to starve the carb of air with your hands. It should purge any small debris out of the carb jets. If it works, there's the problem. Check over the mounting bolts on the manifold to make sure you don't have any air leaks. A spray of WD while it's running will expose any leaks (you should know the drill on this one)
