Engine Cutting Out! What to check?

This may be off topic a bit but I did have an alternator take a chitt inside the unit after some really hard runs with my 410 4 spd. Symptoms of a bad low RPM miss that I could not find. I was under the hood revving the car and the alternator had a dead short in it when I revved it up. Sparks and chitt flying everywhere just over 2500 RPM. Crazy *** miss too. Went to napa and got a new one on warranty. Fixed the ignition problem.
