Plymouth dies in the middle of an intersection and won't start

Had same problem with my challenger.
After MUCH searching,replacing parts and head scratching it ended up being bad ammeter connections.Not the wires to the ammeter but the post connections inside.
This was a "glad I found that" situation as this could have been so close to one of those notorious ammeter caused fires.
solution...bypass the ammeter.Just bolt the two wires to one terminal and fit a volt guage.
