For startes its a 1983 xlt with an aftermarket 351w.
Had a mallory unilite with a msd street fire coil.
Currently had a dsII magnetic dizzy with new streefire coil and 4pin module.

So I have had no issues with my bronco once I got it all up and running until a couple days ago.

First time: Was driving along doing 55 at about 2500 rpm then the engine just died. Pulled over and waited a moment and tried it again and it fired right up.

second time: was just a couple days later. I was running it in my driveway checking out everything and just about to leave. turned it off got my gear in the truck and it wouldn't start. after a bit of checking I narrowed it down to the coil. it was not making spark when grounding out the negative with the positive getting 12v. So I replace the coil and it fired right back up.

Third time: I was driving along a couple days later doing 70 at 3k rpms and it just shut off. I restarted it and kept going. It did it again a few more miles down the road. Then I got to where I was going and after it sat for a bit I tried to leave the parking lot. It died right on the road. I got it restarted and it died again. I made back into a parking spot and it was idling fine. So I opened the hood and was looking at everything. Revved it to about 2k and it died and would not start.

Left it sit for about 30 min and it fired right back up. but once it got warmed up I tried to go and it died again.

So I gave up and left it sit. Went home and bought a new dizzy and module. Its a setup called dirt cheap ignition check it out.

Went back and installed everything in the parking lot. it fired right up and ran fine. Started driving home and it died again after about 15 min.

So I towed it home today and I have a dsII dizzy installed with a gm 350 4 pin module and its totally dead wont run.

I'm sure I can go back to my mallory unilite and I bet it will run fine till it warms up then die.

Does any of this nightmare sound like something to anyone? I'm totally stressed and have no ideas besides checking the wiring which i have been but I cant find anything.

Thanks for any help! I need it.
