It just died while i was driving it.
Sounds like the serpentine belt (AKA fan belt) may have broken or come loose. You'd know this if you saw any lights come on when your car stopped accelerating.
Next, it could be the alternator went bad while you were driving, then when the battery went dead, the fuel pump shut off and you had no more fuel running to the engine.
Finally, (as far as I can think of with out diagnosing the car myself) it may be the timing chain/belt may have broken. I had a 1994 Chevy Cavalier with this problem, driving down the road, everything's fine, I heard a little "pop"and the engine died and I couldn't get it restarted.
When you are driving at a higher speed, the transmission will stay in gear (if you're still in drive) and rotate the engine (although the engine is no longer firing) until you slow down to a speed where the trans realizes there's no more power and it disengages the torque converter to prevent damage to the engine.
So, 3 things to have your mechanic check in order (or yourself if you like) serpentine(fan) belt, alternator, timing chain/belt. The serpentine belt is on the front of the engine, if it's front wheel drive the engine is turned 90 degrees and the belt is on either the passenger or driver's side. The alternator (probably needing to be tested at an auto parts store) is near the top of the engine, attached to the serpentine belt with wires (not hoses or tubes) coming out of the back and if you look in the holes around the alternator case, it looks like an electric motor. The timing chain/belt is usually an internal part and will need to be found with the manuals listed above or a professional will have to fix this problem. All cars and engines have it in different places, but this is what times the intake and exhaust valves to open and close at the right time to keep the engine running.
If you are still having problems, reply to this thread so we can help you figure out exactly what's going on and we'll know what we've tried already. I hope this helps. Good luck and don't forget to rate!
