After driving for a few hours when I stop jeep dies cranks right back up

Hello, You may be having an issue with your EGR valve sticking open, which creates a simulated vacuum leak, or the torque converter clutch lockup solenoid could be sticking, preventing the transmission from disengaging when you stop. This would cause the engine to begin stalling when the engine speed reaches about 1,000 RPM and lower, finally shutting off around 350-500 RPM, and engine speed would directly correlate to transmission speed once in 1st or 2nd gear. .
