Question edited for clarity.Question moved to model category.It could be many things and it is no good guessing. An auto electrician can connect a professional grade scan tool computer and record what happens at the moment it stalls. It is more cost effective that guessing and swapping out parts.

Alarm Module Reset Procedure
NOTE: This information applies to a Vehicle Theft Security System (VTSS) that was armed when the battery was disconnected and reconnected.
When the armed VTSS senses that the battery has been disconnected and reconnected, it enters its power-up mode. In the power-up mode the alarm system remains armed following a battery failure or disconnect. If the VTSS was armed prior to a battery disconnect or failure, the system will have to be actively or passively disarmed following a battery reconnection.
The power-up mode will also apply if the battery goes dead while the system is armed and battery jump-starting is attempted. The engine no-run feature will prevent the engine from starting until the alarm system has been actively or passively disarmed.
Passive disarming of the Vehicle Theft Security System (VTSS) occurs when the vehicle is unlocked using the key to unlock either front door or the lift gate. Active disarming of the VTSS occurs when the vehicle is unlocked by depressing the Unlock button of the Remote Keyless Entry (RKE) transmitter.
Once the alarm has been activated (horn sounding, lights flashing, and the engine no-run feature), either disarming method will deactivate the alarm.
Depressing the Panic button (if equipped) on the RKE transmitter will also disarm the VTSS, but the horn will sound and the lights will flash for about three minutes as part of the Panic feature. The horn and lights can be stopped by pressing any of the RKE transmitter's buttons or driving the vehicle above 15 mph.

If computer sees no crank sensor signal it shuts down pulses to the injectors. But, you bring something new into the mix. Make sure fender grounding is good so the relay can operate properly and make sure power going to it is not restricted by a loose or dirty contact on the power side.

It appears that mine is located on drivers side fender to the right front of the booster

Fuel pump failure. Have someone open your gas cap an listen closely while you try to start the car. Your listening for a buzzing noises, if no noise pump has failed, very weak noise not enough pumping pressure to start the car. All 'n All "FUEL PUMP FAILURE"

you have dash lamps acting funny? diesel engine? or gas, and what displacement? 4.0 , 4.7 P1686 did the immo lamp glow. did you scan the PCM and see if 1685 (wrong key code) 1686, rigth out of fsm Trouble Code: P1686 4.7L No SKIM Bus Messages Received Number of Trips to Set Code: 1 PCM details. Trouble Code Conditions: Engine started; and the PCM did not detect any MIC (I/P Cluster) messages over the Data Bus circuit for 20 seconds. Possible Causes:

• Data Bus circuit from MIC to the PCM is damaged or it is open
• Instrument Cluster is damaged or has failed
• PCM unable to communicate with the Instrument Cluster
• PCM has failed

this means, the PCM can not talk to the I/P cluster puter. comm fail. even wilder guess is PCM talks to KEY via cluster so if cluster dead so be key. bad fuses ? the FSm dont cover defeating any alrarms or IMMO less crooks read it. so...... google it.

Jeep had alot of problems with the lock accuator in the tailgate.

sounds like burnt out bulb. This is usually an indication when the bulb blows. Turn on blinker and check front and back to see which bulb is out..

Jeep has always had a problem down the line with the shifter linkage usuallly under the shifter, you have to take apart the console or column and locate whats broken inside there. I've had this issue myself with Cherokees too .

Watch this video. It is on a 2000 but may be close to the same as a 1999. https://www.youtube.com/watch?v=lBwpusnz8cE

In the fuel evap system you may have a defective leak detection pump.
