My 2000 galant 4 cyl has been continually shutting off while driving. It will do it 3 to 6 times during my 20 minute commute each day. As soon as I pull over and stop, put it in park, it will then restart within 1 minute if not immediately. When this happens no signs appear saying anything is wrong, no dash warning lights or anything. It just turns off. I cant seem to figure out what is causing this. It isnt the fuel pump relay (i changed that). I can work on the mechanics but with a potential electronic issue I dont know where to start or what may be a common cause for this. Any help or ideas would be greatly appreciated.
