96 jeep grand cherokee laredo I have the same thing

I would not change the computer, as I have 2 to 3 times and it does not help. I would look at the wiring harness (fuse box) in the engine and play round with the wires. This is where I'm at with my jeep I have put 3,000 in to my jeep for this problem I have changed all kinds of sensors crank shaft, cam shaft OS computer 3rd time and much much more still doing the same thing fuel pump is fine. I think there is a short some were that keeps shutting the engine off.
