This is the same problem i have been happening with my car. What fixed my car is redoing the wiring leading to the postive wire to the ignition module. Those wires have little circuit breakers that can sometimes heat up and cause that problem. I would check that first because i replaced my tfi, distributor, ignition coil, and it would still do the samething. The wiring was just bad. Hope that helps you out.

your CTS could be bad. When they read too high it will shut of the injectors and ignition.
