First of all make sure you are checking the fluid right. Some people do not know that in order to check transmission fluid the engine needs to be running and the temperature needs to be sort of warm althought you should be able to get a good Idea just by the engine running. In this instance you might have a governer valve that isn't properly working to shift the engine when hydraulic pressure reaches a certain PSI. I would suggest having it flushed and put in new fluid and filter. If this doesn't work the problem is more serious and might need some professional assistance.

Have you ever cleaned the throttle valve and idle speed control valve? this is on the stall issue. the starter sounds like the contacts may be burnt in the starter solenoid, this is common on this type of Japanese starter at about this mileage, you can rebuild the starter solenoid or just replace it.

I would check to be sure that the timing chain hasn't jumped at all ..

This started happening on my 05, 3.7L at around 45K miles. Usually once every two months, then I would shut off and back on and everything would be fine... Happened last week and I took to a private mechanic... Private mechanic said TCM needed to be flashed, and maybe replaced... Dealer said it would need to be replaced (of course)...I just got back from Dealer and it was covered under Powertrain warranty (only to 70K), but still cost $500 to replace the circuit board under the shifter... I dont think it shouldve cost that much, but I followed their advice so it hopefully wont happen again... Third jeep, each successsive one (each newer than the last) has more and more problems... Its sad that this will be my last jeep product...
