The vehicle has had an oil change and replacement of the power steering pump, reservoir and hoses. After starting the car and driving for a short while the engine shuts off and the ''service engine soon'' light appears. The car can be restarted immediately the the light stays on and the engine will shut off. This occurs as long as I drive the car. The engine has shut off while I was driving down the free-way. For that reason, I don't drive the car.
It is most likely a crank sensor!!!!!!! i am 99.9999% positive that this is the culprit. I am a mechanic and this is the first thing i would check with your description.

if serpentine, then it should be on the fan shroud or the radiator cover...
SOURCE: Power steering reservoir location
As you are looking at the engine from the front, it is at the back left, a little under and inside the rear serpentine belt pullies. It's hard to see, but if you look from the inside, down the back of the motor by the firewall toward the belt pullies, you should be able to find it. It is more difficult to access if it with a turbo. No wonder GM is going down the drain. :D

This pump sits down below tha alternator. If it does not have a remote resevoir than the resevoir sits on top of the pump. It is a pain to get to.

you can rent a puller from one of the performance companies out there. I believe the one is 3800 performance? Or ZZP
The nylon coupler wears out and rattles like the sound of rocks within it. My bearings were perfect
