I have a 95 galant. I was driving it at 60mph when it just shut off. Lights, radio etc. still worked. I got off the road and it started back up. Several weeks later it did the same thing but wouldn't start. Check for spark and didn't have any. Changed the wires, plugs, cap, router. Started up and ran great for about 10 minutes. Then died again. Some friends suggested a distributor module. So I got one, replaced it. Started up and ran great. Took it for a quick spin, no problem. On the way home it just shut off again. Lights radio etc. work fine.

Any ideas?
