Ive been having the most annoying ignition electrical problem for awhile now. My 62 runs rough and really rough after it after getting hot. Sometimes after getting hot it will stall and won't start up for approximately 15 minutes, and then it will start up and I can drive it. I previously had the coil, distributor, cap, and plug wires all replaced and it was fine for a couple weeks and then started to act up again. It had an aftermarket coil on it before (it was called a fire something) that had a crack in it which was placed with a Toyota coil. So all the stuff is new except the ignition module which is a dyna mod. I was wodering if this module could be causing the problem being the coil is now a factory coil do I need to go back to the stock ignition module (really expensive). Thanks in advance for any help I hoped I explained the problem.
