Hey guys I have a 1994 cobra and am having ignition problems such as the car just shuts off on its own and will not restart due to no spark and all ignition parts have been replaced some times i will regain spark and it fires right up and will run fine for a little while or just until i turn the car off any ideas on what this might be would be of great help.

i replaced all the electronics inside the distridutor as well as the cap and rotor, ignition control module, coil, plugs, wires and tps and those were all replaced last month and the plugs and wires were done about three months ago i have fuel presure and it is getting into the cylinders just no spark at all. The rotor is turning while i crank the car all parts are stock replacement except the coil, cap, rotor,and wires they are all msd and i tried the stock coil and had no changes.

Ok so i have ran all the test described in the link that was posted and even though some parts did not need changing out i did it anyways such as the coil and ignition control module i also replaced the battery and now the car will crank and run for about 1to 2 miles then loses spark again and will not run untill it cools back down to ambient temp also i was wondering if any one knows what the resistor/diode? is that is mounted to the back side of the bracket for the coil because i changed it out with the closest thing i could find at the parts store and then the car would run like it is now any more ideas on this issue would be greatly appreciated. Also replased the three relay boxes in the fuse box under the hood.
