Good afternoon and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 18 years and I will do my best to help.

When it stalls are you loosing spark or fuel psi?

Customer: replied 9 months ago.
it acts like the power to the computer is cut off and than come back on when restarting. for the last 5 yrs the car had check engine light on because of low vac leek. after this cut off problem started the engine light went off. like power was cut off to computer.

In order for me to help you fix it, I will need to know if your loosing spark or fuel psi... Are you going to be doing the repairs or are you just looking at what could be wrong?

So your saying you have tested the PCM and it's loosing 12v when it stalls? Have you tested for spark and fuel psi when it stalls?
