Un-metered intake air is known to cause this issue. Make sure you have the Air Flow Meter (AFM) installed, connected, and is sitting level (it uses a flap to measure incoming air so if it's not level the flap may be affected by gravity and the reading may be off). Also check for major vacuum leaks. The car runs because the ECU ignores the AFM during startup but as soon as it switches from the "start" sequence to "run" the car dies because the AFM reading is too far off from what's actually making it into the intake.
