97 XJ Stallling

Hey guys, hope someone can give me a hand here... My 97 XJ 4.0 auto stalls (completely dies, no warning just dies no rough idle, hesitation etc dies) when I am sitting in stop & go traffic and the temp gets a few degrees above normal... When it dies, the temp is just slightly above 210, its not like its overheating or anything... If the temp goes slightly above 210 (a quarter of the way between 210 and the next white mark) it dies... So it only happens if I'm sitting still in traffic on a very hot day... After it dies, it turns over but does not crank... Let it sit for 15 min and all is well, cranks up and drive off with no further issues. Its done it 7 or 8 times in the past year... In the past year the following have been replaced/upgraded; new header, flowmater 50 series and magnaflow high flow converter & both O2 Sensors; new Firepower 4.0 ignition kit (wires, coil, cap , rotor and plugs) new Rustys motor mounts, new CPS, TPS and NSS.... I have checked when it dies and I have fuel at the rail when it dies... Sounds like maybe a sensor or relay getting hot but????? Also, it was doing this before any upgrades... Maybe ASD relay, CPS PCM??? Thanks for any help...

I was having the same problem with my 97XJ. It eventually got to the point that it was doing it more and more and then just running like crap. It was really simple for me. Not sure if it will work for you, but it worked for me and is very easy. So its worth a shot and will cost you $0.00.
