i will say possible blockage in fuel ine somewhere between tank and injection. start ththe car wait till the car is warm then try to floor it while it is idling and before it dies, if that doesnt work try a fuel cleaner. basically tip it into the tank before you fill it

Clean or replace the Idle Air Control valve. It's positioned in front of the throttle body. Hasa two wire electrical hook-up.

check for a bad cat. internal restriction in your exaust sys will generate excessive back pressure and cause your motor to quit. good luck

Coil pack's toast. Replace it with one from the wrecker, should be about 25$.
