Mine died completely one day after driving it in 102* weather with the AC on due to a Crank sensor. At first we thought it was plugs, wires, cap & rotor (since they were due about 600 miles prior) so we did those & the cam/pick-up sensor. Still nothing. Replaced the Crank sensor & it started right up. BUT, it gained this "miss". When just starting out at a light, stop sign, it drops RPM's & sounds like it didnt fire a piston... When we get up to about 50, it feels like the drivetrain is going to fall out the bottom of the thing, so obviously, we dont do that no more. A lack of better terms, it feels like it's binding up on the powertrain side somewhere. there is also what looks to be water in my oil might be due to a water hose that cracked and i replaced but i am unsure. I cant seem to figure this out. I replaced the fuel filter, fuel pump, ran fuel injector through it, the pressure on the rail is normal according to a garage, it's throwing no codes, nothing comes up on scanners.... I'm at a complete loss. Any help would be appreciated!

Nothing comes up on scanner at all ?

Recheck the firing order and make sure the plugs are gapped right.

did you use a Mopar crank sensor? if not, you should have. from what ive heard, these jeeps only like Mopar sensors, and an aftermarket one could very well be your problem

"looks like water in my oil"? sounds like maybe a blown head gasket. When you check plug gaps, look at plugs for residue and consider a cylinder pressure test, too.
