What year XJ, what engine, what transmission ?


Is the Check Engine Light (CEL) ON ? How many miles since the last tune-up ?

A bad battery, bad battery wire connections, other faulty wire connections, a faulty O2 sensor, a faulty CranKshaft Position Sensor (CPS), or a failing fuel pump could be the cause of the stalling.

You need to perform some routine maintenance/cleaning, some inspection, and some electrical testing.

Start with testing the CPS.

Fixing the Check Engine Light problem should be your first step.

You should resolve any check engine light. Even if the engine is running fine, if you don't resolve it and you have more codes, it makes it very confusing to figure out what is what and you don't know if the first code issue has a relationship to the others.

For your 95, it's easy to retrieve the codes. Here's how. Post the code number(s) that you find for comment.
------------------------------------------------------------------------------------------
Retrieving OBD codes on the Jeep Cherokee (XJ)

OBD1 Models: 1991-1995

1) Start engine (if possible). Move transmission shift lever
through all positions, ending in Park. Turn A/C switch on and then off
(if equipped).
2) Turn engine off. Without starting engine again, turn
ignition on, off, on, off and on within 5 seconds. Record 2-digit
fault codes as displayed by flashing MIL.
3) For example, fault code 23 is displayed as flash, flash,
4-second pause, flash, flash, flash. After a slightly longer pause,
other codes stored are displayed in numerical order. When MIL begins
to flash fault codes, it cannot be stopped. Start over if count is
lost.

NOTE: A "5-5" will always occur to signal the end of the sequence. Some will flash the "1-2" code indicating a recent battery disconnect even if you haven't done it. Ignore these two codes, and mark down all others.

How old is the battery? Even if it's "good" enough to start the jeep, it may be low enough to cause a problem. It's kind of strange, but one symptom of a battery going bad in an XJ is extremely low idle. The automatics will idle so slow that they'll die at stop lights - can't stay running with the vehicle in gear.
the problem will e intermittent for weeks until you finally have a problem cranking to start.
