I have the same problem at the moment,it quit doing it for about a week now its starting to do it again,sometimes it does it while going down the road.Also sometimes while Im driving it will just lose power, the motor will still be running tach will still be working and all,Feels identical to a car that has hit its speed limiter.Also when it dies at idle sometimes its hard to crank but if I let it sit for about 10 seconds or so and let the fuel pump kick on it will start up just fine.

I used to have a 93 Trans Am that this exact same problem happened on. I replaced what they called a ignition control module. It is right above the coil pack. Its the sensor that has a plug going to it. I got mine at autozone for 40 bucks. I hope this helps.
