I had a coil failure last year. The coil was an MSD Blaster II, epoxy filled, mounted vertically to the front of the cylinder head. Car would start and run fine, but occasionally while driving the engine would just turn off for a second or two, then come back on.

I replaced the coil and added a couple of nylon washers between the coil bracket and head in an effort to get some thermal isolation between the head and coil. It has worked fine ever since, but I have only put about 1,000 miles on the new coil.
