Hi All
Thanks for the help so far - I will do some more testing this weekend if I can - I now have two suggestions about the coil - I did not realize that it can fail at high temp - I was going to heat it with a heat gun I have and see if I get spark - I dont know any other way to test it.
The condenser suggestion above is also interesting. If I remember correctly, the condenser is just a capacitor, and i am guessing the dielectric material in it fails with high temps?
Ignition coil and condenser are also pretty cheap, so I might just replace them and test the old ones off vehicle - For now, I will make sure I shut down when in a driveway waiting - has not happened at a long traffic light yet - that is my real worry
