My 96 dodge ram loses spark once everything under the hood gets warm, If I drive it down the road it is fine, when I come to a stop and it idles for a few minutes it dies no spark. If you leave it sit 45 minutes it will fire right up and be fine again till you stop moving? I replaced the coil and the crank sensor. Help?

Subject: 96 dodge ram with no spark
what is a coil driver? The computer itself? Should I replace the computer? I've tried a different asd relay, thank you

I gave you the ASD relay bcuz it powers the coil -Now the col driver is integrated with the computer-this is the one that switches the coil primary to fire the plugs-

So the coil driver is the computer? I can get as used computer from salvage yard for 125. Should I try that? Or where is the coil driver?
