To the OP:

You need to check for voltage at +lead of coil when your car dies. If not voltage, it can be anything of what was mentioned… ballast resistor, bulkhead, ign switch, ign switch plug down the column.

If you still get voltage, it could be coil itself, pickup coil into the dist, or ECU.

Sharing a similar experience I had long time ago… couple of times when engine stalled I found shaking the distributor pickup plug it started again. It was a bad contact somehwre between plugs or pickup coil pigtail. The pickup coil itself was good but maybe the wires into the molded plug were broken/loosen. Didn’t replaced the pickup coil but just the plug.
