1990 Buick lasebra dies while driving???

Can someone please help me?? I have a 1990 Buick and last night I was driving it and everything was fine I drove to a friends house, home and then to pick bf from work... Everything ran the same as always... But on the way home it just died while we were driving... The only thing that changed in the way we use the car is I got a new fm transmiter for my iPod and I use it in the cig lighter for about 5 mins... Just to pick him up... What would make this happen??? The car started back up after it died but it would died agian after like a min or two... Please help

Missing lots of info, do you have spark to the plugs, how about fuel pressure at the port in the rail?
