It goes dead as in absolutely everything shuts off? do your hazards work when the jeep is "dead"? Or brake lights? Have you checked any fuses under the hood? Check for power at the main 40amp fuses, 4 or 5 of them in there. Check that you have a good ground, terminals are not cracked and are tight. Check that the connection to the PDC under the hood is good.

most likely the ignition switch/actuator pin

So, you say that when you "wiggle" the key, you activate the entire ignition system which, includes all instrument panel operations, correct? That to me, would indicate something still faulty in or around the ignition key/switch etc.

Basically, through the ignition switch, you send a signal to the solenoid on the starter. That, in turn, (no pun intended) connects BIG POWER, from the large battery cable, on one side of the solenoid on the starter, to the other side of the solenoid and, that kicks in the bendix and, at the same time, spins the starter which, spins the motor.

But, you're not getting that far. Your energizing of the total ignition system is ceasing at the ignition switch 'cause you're not even getting the instrument panel to light up unless you jiggle the switch. So, I'd dig around in or around that ignition switch and it's related components to see what I could find.
Good luck.

Before all this started happening, did your ignition key have a big bungle of keys or a lot of weight on your key chain? Usually new ignition switch, will not have the key insert with it, you insert that, into the new switch. You might need a new key insert, for your switch, that wiggling, kinda indicates that. This could also be a combination of two or three things, one failure leading or causing another. That is really hard to narrow down, if that is the case.
