After about 15 miles I get intermittent miss and it will die when coasting. on 1993 Jeep Grand Cherokee

It fires right back up after it dies but the intermittent miss is still there until it has sat for a couple hours then it will run fine for about 15 miles. It has new tune up plugs wires cap & rotor. new fuel filter and fuel pressure regulator. no check engine lights.

Crank sensor is most likely to blame
I have also noticed a voltage drop on the in dash volt meter at the same time from around 13.4 volt to 12.4 volt. could this be related?
I have seem many Jeep crank sensors fail. Usually when they get hot. I would have a professional check it to be sure.
