4 Wheel Drive/SUVs: Stalling, jeep cherokee, temperature sensors

Question
I have a 1990 Jeep Cherokee Pioneer. I gave someone a jump start a few weeks ago and now it just cuts out when the temperature goes over 100 degrees celcius and will not restrat until i cools down to almost 0. Also the auxillary fan does not come on. I have relplaced the thermostate, the ingnition coil and the rotor.I was told that there was a computer part that may be bad that sits under the distributor, but there doesn't seem to be one. Help me if you can.

Answer
Chuck,

There is a good chance that you burned out  an electronic component when you jumped the other vehicle.  

When you do give another vehicle a jump, you need to make sure that someone stands by the cables, and disconnects the ground cable as soon as the other vehicle starts.  In reality, it is not a good idea to jump cars.  With the newer cars, the electronics are fairly sensitive to voltage jumps, and when the dead vehicle starts, the voltage can surge high enough to affect your car.

It sounds like the problem is in one of the temperature sensors, and not in the distributer.

I would take the Jeep to a reputable automotive electrical shop, and have them check it out, and see what sensor may have burned out.
