Is the Check Engine Light indicating?

After it cuts off, were you able to restart?

See if the following is of any help.

STALLS AFTER STARTING

Symptom Definition

Engine starts okay but dies after brief idle, dies as soon as any load is placed on engine (such as turning on air conditioner or engaging transmission), or on initial driveaway.

Possible Cause & Correction

Check the following items:

Make sure that hot air tube is connected to air cleaner.

Check for proper operation of thermostatic air cleaner.

Check for proper operation of Idle Air Control (IAC) system. See appropriate component CHART C-2 for that system.

Check PCV valve for proper operation.

Unplug MAF sensor (if equipped). ECM will substitute a default value for MAF signal. If stall condition is eliminated, replace MAF sensor.

Check EGR system for proper operation. See appropriate component CHART C-7 for that system.

If stall occurs when air conditioner is turned on, check for air conditioner clutch signal to ECM terminal. Voltage at A/C terminal of ECM should be battery voltage when air conditioner compressor clutch is engaged. A high voltage surge due to a shorted compressor clutch diode could cause ECM shutdown.

Check for an overcharged air conditioner system.

Check for plugged or restricted fuel lines. See appropriate component CHART A-7, FUEL SYSTEM DIAGNOSIS for that system.

Using Spark Tester (ST-125 ), check for a weak spark from ignition coil.
