This happened to me in my '68 GT en route on a ski trip in real isolated,
snow-covered terrain. Running super-fine one second, dead as a stone the next.
Turned out it was that wire at the base of the distributor--I forget, is that
the capacitor?--had flexed one time too many and broke off. My girl friend was
really impressed when I brought the car back to life with just a small piece of
electrical tape. Me, I was stunned.
