Allright Gurus, Can't figure this one out. It's an 87 with a coil outside the cap HEI setup. A new OEM distributer installed last summer, and a TBI intake. Occasionally the truck just won't start or will die while cruising. It just cuts out and I have checked it to find that there is no spark. However, the problem is intermitant and all of a sudden the spark comes back and the truck fires right up. It does not sputter during acceleration or any other time. It does not idle rough and there does not seem to be any pattern to the problem. Any ideas or suggestions?
