Why would your car shut off while you were driving and it will not start or turn over?

I had a Dodge omni that did that exact thing and it turned out to be a $15.00 part that was located under the distributor. I forgot the name of the part though. .

Answerthis same problem happened to me..i have yet to solve it tho. it was running, then it started running rough so i pulled over to take a look under the hood. It never did turn back on..(84 Toyota celica)

Well this happened to me, i ad to change the ignition module and it ran just fine

If it doesn't start or even turn over, I would suspect you have a dead battery possibly from an alternator that failed.
