Engine shuts down!

Do you know what you are loosing when the engine stops running ?

You'll need to figure out if you are loosing spark or fuel pressure when it stops running.
I would say it is something electrical, could be anything from the ignition module to a relay.

If I crank the motor while it is st ??????? Probably ignition module . When it shuts off check for spark .

Engine stalls cold or RPM fluctuates at idle up and down or dies near idle.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control. If the above cleaning doesn't cure your issues you need to have the computer controlled automatic idle speed control system diagnosed and repaired by a dealer or electronic engine control repair shop.

Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve.

A vaccum hose or an electrical connector may have been disconnected during the repair. Check the battery itself by the way.

the egr valve is closed when the engine is cold.
when the engine is warmed up it opens
if closed when warm the engine dies out
check that item out next

First thing is to check all the fuses...next would be to look for a burned wire....in the harness that runs behinf the engine.

possibly a bad module------cracked---or???? In any case you may get expansion as engine compartment warms up----module shuts you down. Sometimes really hard to diagnose and just putting in a new module is "spendy"----especially if it turns out not to solve the problem!

done the same in my volvo it was disrubitor but make certain that replacement one the same part number.
