It sounds like the engine has developed a miss. Have you checked plug wires to make sure they are good, tightly on the plugs, and not arching? That would be my first guess. Also, check / listen for vacuum leaks.
Finally, if you can take the car to an Auto Zone or other nationally recognized parts store, they can scan the computer for trouble codes. Most will do it for free.
Let me know what you find.
