Did you get your "no start" condition figured out Mark? Might be the ignition switch. You said it bumps the motor when you cycle it off. Next time it acts up try cranking it and backing off the key a little bit and see if that fires it. Or check for coil power while cranking.
Hi BP... I pulled the plugs off the bulk head inside the engine compartment and the terminals need to be cleaned up. I'll get some terminal cleaner today and hopefully that will solve the problem. The coil checked out fine. Thanks for the tips.
