Engine popped back thru carb and died, no start issue

Hopefully it won't embarrass you again. I have had a no start twice, embarrassing in front of people. It had something, for me, to do with ign. Something with the coil, ballast and or the chrome module. Ended up being a bad coil. But I think about it every time I have people around when I start the car. Try and remember the area that changed things. That's the trouble with doing several things at a time, when it works, your not sure which one was the problem. I do this all the time! So if it happens again......
