I would check the coil, and doe's the vehichle's starter drag when you try to re start it, if so, you could very possible have a bad starter, that is heating up after the vehichle is driven for a while , this is due to the starter armature expanding, and not allowing the starter to start correctly.

It sounds like the ignition coil is over-heating.

1998 cherokee stall when driving and gets warm ,And wont start till it cools off ?


does your temp gage seem off does it go like up to the h because if it does you could try unpluging your upper coolent sensor because that could cause that because it is telling you computer to run in closed loop when it should be running in open loop

1994 Grand Cherokee, 5.2 V8 shuts off when hot. Cool for an hour or 2, starts up after a half hour or so, then dies again. No trouble codes except 12 and 55; I pulled fuses to check them, hence the code...


NOTE: With the jeep cherokees. the Check Engine light if continuously driven with it on for more than 25 minutes whilst still traveling will engage the "PCM self protect" usually around the 27minute mark,and shut down the vehicle, and yes it takes 90 minutes to reset,

you might find that you will arrive ok, at your destination with this issue... pull up, and then it wont start again a few minutes later, this is the PCM Shutdown protection.....when the check engine light is on means the PCM is reset,found the error and why you can only run the car with the check engine light for about half an hour.

"You can however drive and turn the car off and coast in neutral and turn on the vehicle again to buy yourself more time with the "Check Engine time limit shutoff"

happened to me in mine, the error codes never showed up for the crankshaft position sensor
either...

i replaced the crankshaft position sensor under the transmission case, and it got rid of the issue this crank sensor is a common cause of the cherokees , it could no longer read the speed of the crankteeth. and can't get a reading the car is still running hence the shutdown, also you will find it also controls the PCM to engage your second fan on the radiator because it cant tell the vehicle is still running, and causes the PCM to get confused and wont let the rest of the engine function properly ie: coolant sensors, and Thermostat sensors, and you will find it overheats and needs to cool some times...which is why the PCM shutsdown the car.....try the crankshaft position sensor replacement under the transmission it's usually the cause of this on all cherokees "makes no difference if its a V8 or not by the way, same thing happens on 4.0 straight six engines also" .

it's in your auto start system. mine does the same thing. after it sets fot 5 mins. it starts. if it is a factory installed auto-start, have dealer check. if it was installed by someone else, theirs a problem with installation or wired wrong.

Your engine computer is bad. It's a good thing that you mentioned about the check engine light dying also, as this is a classic sign of a bad ecm. I have repaired more than one of these Jeep computers, replacing the three power capacitors located inside the computer, and they have worked for years afterwards. If you don't have the skills or knowledge to repair the ecm, get yourself a rebuilt ecm unit and swap it out.

Jeep grand cherokee stalls after warming up


You need to check components again when the engine is hot and in no-start condition, otherwise, you will get bad info...obviously whichever part is doing this works fine cold. ones that react most to heat are crank pickup, ignition coil and the fuel pump.(bad ones get hot and bind up)
