'93 ignition coil probs

So like most 4.0 mine runs hot when pushed. However, it seems like if I run it "hot" for longer than a half hour, hot meaning slightly over 210, the ignition coil dies. I can't tell you how embarassing it is to have the Jeep on the side of the road. This isn't the only reason the coil dies, however, I've gone through 5 in the last 6 years I've owned the vehicle. Any ideas as to what it is causing this??

I realize it is fairly inexpensive, but I'm really annoyed that they only last a year or so. I bought one from NAPA and it only lasted 8 miles. Ya enraged They were nice enough to refund me though. So my thought is to save it from heat, because heat destroys these coils, is to move it closer to the fender and make a heat shield. Any thoughts??

Isn't red the only color a vehicle should be?
If at first you don't succeed, use more speed.
