1993 Buick Park Avenue • 215 miles

I have driven this car for approx 4 months, and I have a recurring problem that I can't seem to fix. Even my mechanic just called me and said that he can't find it either.
Here's what happens:

I will be driving down the road and the car will just kill. The entire warning light system goes on and if I try to re-start it, it will take a couple of times and then it will start. In the past it would happen one or two times and then nothing more. Last Sat night I tried to go to Walmart which is approx 5 miles away and it stalled at least 15 times from my house to Walmart and back.
What can be causing this? My car is immaculate, full power, and everything works.
I really need an answer, so I hope that you can help me. Thank you very much.
