Hello,

Well, there could be several things that can cause your problem. So, Lets start with a few questions so I can give you a better diagnostic.

1) Is your check engine light on? If so we need to see about getting codes pulled.

2) When you start the vehicle can you press the gas peddle or pulse the gas peddle to keep it running?

It could be the TBS (Thottle Possition Sensor), MAP (Manifold Absolute Pressure Sensor), Fuel Pump or Fuel Pressure Regulator.
