May could be a bad altenator regulator allowing a power surge.

When it quits, and won't restart check to see if you have any power going to the ignition system.

Did you put the dielectric/heat transfer compound on the back of your HEI module to help transfer the heat, it usually comes with the unit, if new in the box.

What brand is the HEI units?

Are you also replacing the pickup coil, if not do so,

Check to see if it has the ground strap that goes to the coil from the center terminal. Sometimes people that are not aware will leave this piece out. Or loose wire going to the distributor. Especially if the clip that holds it on the distributor has been broken.
