My car was doing that last year. It would be idling and then for no reason just cut out. It was hard to start after that, and when it would start it would stall after minutes of driving it. This left me stranded one evening and I had to get it towed home. The next day I put a new coil and still nothing. I finally purchased a $10.00 after market ignition switch and installed it under the dash. Cranked right up and has been fine ever since. It's been like that for 9 months or so. I took apart the original switch and cleaned it up and plan on reinstalling it soon. Let us know what you find out.
