Yesterday, I drove for about 4 hours with the AC on full blast (it was low on freon and not blowing out very cold air). When I hit traffic, and was just crawling along, the car would die. Usually, I could start it right back up again but twice, I was left stranded in the middle of a very busy interstate (I295 in NJ)for 10 to 15 minutes. The temp gauge never rose above normal. Very scary.
Anyone have any idea on what might be wrong? The local Ford mechanic is stumped and my warranty expires in less than 1000 miles.
