sounds like your injectors aren't firing.

 

Have you checked your fuel pressure?

If you have pressure, then your injectors ain't working...like Thunder said.

"Something" tells the injectors to get with it, get working, NOW!!! It could be the computer, it could be a sensor, whatever it is...start there.
