This just started to happen I'll be driving down the road and she die's as if I turned off the key. If I let it set for 10 minutes or so she fires right back up and drives fine. Now yesterday after waiting it started and only ran for about a 1/4 mile then died again but after waiting another 10 min she got me back home no issues. This problem has me stumped as the engine runs fine otherwise smooth as silk no misses and no rough idle. Any help would be greatly appreciated thank's. "03" WJ 4.0L, select trac, 75,000 miles on er.

 

what happens if you try to start it before the 10 minutes? When she dies, does your dash panel light up or does it go completely dead? Are you getting any codes?

 

No codes no check engine light last time out it did start up before 10 minutes just died again within a 1/4 mile seems electrical was thinking maybe coil pack?

 

It's possible. But the 4.0 wouldn't die if it was just one coil pack. I once saw this engine run with two dead cyclinders, it ran like crap, but it ran. Maybe Crank sensor is going out?

 

CPS was the culprit $30 and 2 hours labor in a parking lot after driving it for 20 miles at 93 degrees she was freakin red hot!!!! multible burns and blisters not as easy of a fix as some has said was not easy getting it back in especially the clip on the top and getting the bolt back in just isn't any room to get your hand in there and move it around. Got er done and learned another 4.0L lesson

 

Good to hear you got her done. Until next time. lol...
