2012 2 Dr Sport. It pops out of 4th and grinds sometimes when driving unless I really push it in there and make sure it's in there but doesn't happen all the time. This has been happening since I bought the Jeep in 2013 with 15000 miles. It was completely stock and had never been wheeled.

The other problem I'm having is in the cold mornings if the Jeep isn't above 140ish degrees. Only on the first take off it will loose all power at 1500 RPM's like it ran out of gas and then pick right back up like nothing ever happened.

It has full AFE 3" hi tuck exhaust, cold air intake, throttle body spacer, bully dog GT tuner, 3" teraflex lift with 4.5" fox 2.0 res shocks, full adjustable short control arms, adams 1310 front and rear drive shafts, 4.56 gears with open diffs, and sits on 37" cooper pro sttt's on 17" ATX Slabs.

Any clue what could be wrong?

I remember reading about the boot around the shifter was causing the pop out of gear problem.

Someone else that has had this will chime in.

Can't help with the cold issue 😕

I had an older model Toyota pickup to do this and it turned out to be the plastic bushing on the ball of the shifter were worn. May want to pull your shifter and see it that is your problem.

If if it's acting like it running out of gas could possibly be a fuel filter. Not sure if these Jeeps have an external filter. Haven't work on them enough.
