I have found a couple things that make my 65 vert act weird (no power). One is the headlight switch, and the other is the turn signals in the steering wheel.
The headlight switch, I could jiggle and get power. The sheering wheel, I could turn it back and forth and get power (some times it would shut down while making a turn at low speed).

I have had my car stall while turning the wheel, interesting that you are also seeing that. Maybe I have to start it with the wheels facing forward.... Have to love old cars

The brass shavings from the turn signal contacts were shorting it out. Take off the steering wheel and clean it out.
