It sounds like its not getting either enough spark, (fault with ignition system, timing etc) or not enough fuel (fault with fuel pump, ECU, etc)

First thing you need to do is check for codes on the ECU.

Pull the carpet up on the passangers side and then with the ignition on (but the car not running) watch the little LED light, and count the flashs.
(Im pretty sure thats how it works)
