Thanks for the imput guys. My car has been running pretty much better than ever since last night (I recently added the dmd and cleaned my air filter). Also, we hooked the computer up to it as soon as we got it back and it didn't throw any codes out. I don't think it was a problem with the battery, since my 4 way flashers ran for about 1.5-2 hours after the car shut off. I also had the alternator replaced by ford under warranty about 1-2 years ago(if that says anything

)
On another note, I just heard from talking to my sister who also has a contour, that her mother-in-law, who also has a contour, had the same thing happen to her. She said it only happened when her tank was half full or so, and they realised later that one of the two fuel lines had to be replaced. This is kind of ironic becuase my car shut off right when it was at 1/2 tank

....so I"m not sure if this would have anything to do with it or not. I don't know much about fuel systems, but I have read on here that some tour's have a returnless system and others don't, so I don't know if this would even apply to me.
Just a though, thanks
