i have a 95 grand cherokee with a 4.0... the ignition coil will get hot while driving and shut the enginre off. i bought a new one and connected it when this happened the last time and it shuts off after about 10 miles of driving..my question is , what can cause a coil to overheat? i have correct voltage so it is not overcharging.

Is anything toutching it. like a wire? excell makes one that did the same thing to my jeep, i went back to OE and the problem never came back.
