Not knowing what you have modified, I'll guess that you have an ignition problem (coil, plugs or plug wires faulty). You could also have a fuel pressure problem. How long since you changed your fuel filter?

You could also have a clogged catalytic converter. Are you still running the stock pre-cat (tends to fall apart and clog itself and the main cat at ~50K miles)? How many miles on your car?
