96 Cherokee sport, when I try to start it is as if I have a dead battery, I go under the hood, disconnect battery and reconnect it, turn key and it starts right up. I've been dealing with this for a while and want to get it fixed but no one has heard of this before. Battery and cables have been replaced, new fuel pump, cleaned all grounds, inspected ignition wires.... please help

Check the starter. Had a starter in another vehicle that was failing. It acted like a dead battery. Quick test si starting with the lights on. Does the lights light normal then dim completely when you try starting??

When it happens everything goes dead, it's like I'm resetting the computer, got a pcm from a junk yard, I'm gonna give it a shot, starter is fine it's fairly new

Remove the cable ends and clean them and the posts till they shine, then reinstall them and make sure they are good and tight.
You should not be able to wiggle them or move them in any way with your hands.

Well this is a battery or starter issue. Maybe even an alternator. As suggested above clean both ends of all power and ground connections. Positive post, connector and connections to starter and fuse blocks. Then the same for the ground wires.
Check the battery voltage key off then watch it while starting the vehicle. If you start below 12.6V you have an issue. You could also pull the battery and starter. Then take it to AZ, ORilly's... And have them load test it.
