Having problems with your 1995 GMC Jimmy ?

My 95 jimmy just stops running at hwy speed, pull over turn off and start right back up. I heard that the coilpacks get too hot and conk out. maybe that is why it runs cool (like 70 c) . It has 330,000 km and, bought used at 320,000. other than that the 4.3 vortec doesn't miss a beat. thanks.
