when it dies pull the boot of the coil and place a wrench above the coil and to a ground.
Crank the engine over and see if you get a spark to jump from the coil to the wrench.

Test it before the engine dies and compare.

Im with stepman on this one. I had an MSD box fail something like you described. The MSD has a self test feature to track down these issues not sure about yours.

Just don't be holding the wrench when you're doing that.

Sounds like my old ignition module. Would be running fine, then BOOM...dead as a doornail and wouldn't crank. Let sit for a few minutes, it cools down, and off to the races again. My grandfather said in a pinch I could put ice on the box to cool it down and get it running but I just straight up replaced it before it happened again. It wasn't a mallory kit though, so can't really speak to them with authority...just hearing exactly what happened to me.
