Need a bit more detailed info.
Does your Jeep feel like the Engine is being held back at the time of stalling ?
If you Quickly put it into Nuetral is it ok ?
does it stall any other times?
The Converter clutch in the Torque converter is not releasing properly Thus Just like a stick shift not releasing the clutch when stoped .
I recommend having your 3/4 - TCC (torque Converter clutch) solonoid pack in the transmission replaced
If this has failed it will not allow release of the clutch
