The linkage on my dual carbs (VW Bug) would hit the tail light connector in such a way that it went into the connector where the wire was - but ONLY under hard acceleration at night.
Both had to happen at the same time:
1. Harness had to move backward in the vehicle under Gs (front-to-rear direction)
2. Linkage moving to the full throttle position (up-to-down position).
Battled this for a while. Then one night I had the decklid off cruising with friends (gotta show that motor off) and my friend behind me says "hey, there is a spark from your carb linkage."
Goofy problem located and solved.

Getting slightly off topic, but being a VW owner and fan myself, your story reminded me of mine. For a few years, my turn signal would randomly blow a fuse. Maybe 3x a year. I eventually ran out of 8 amp fuses, so I popped the next size up in the slot. 16 amps! I figured if it was a
real short, the fuse would still blow.
One night on the highway I used my signal and my headlight started blinking! So bizarre! When I got home I tried to reproduce the problem. Not only could I not reproduce it, but the signal wouldn't work and the switch no longer had its detents.
Turns out I had burned out my turn signal switch. The cause? There's a floating terminal junction in the trunk that's insulated with a plastic sleeve. The plastic sleeve had shifted exposing the crimped end of a wire terminal. Depending on the position of the junk in the trunk, the wire might be pressed against the steel and make a low resistance short. Somewhere between 8 and 16 amps!
Lesson learned. Don't use a higher rated fuse than what every component in the circuit is designed to handle!
