Cheque for disconnected vacuum hoses. sometimes this happen after working around the engine, if everything looks good, start the engine press down the accelerator pedal keep the engine running about 2500 rpm for 3 minutes then let the engine idle, if the engine idle this means you need a new idle speed control motor, if the engine still dies most probable the fuel pump it's going out if you have a code reader it's possible you have some codes and this can give a good direction

This idle condition is normal for a cold start, the computer is controlling the idle for proper fuel burn. It is not necessary to wait five minutes for the idle to come down. Allow about one minute before putting into gear and driving.
