1970 Datsun 240Z — car died once at a light and restarted immediately

The engine shut off at a stop once, restarted right away, and has been normal since. No warning stayed on. What data or checks would you prioritize before trusting it on a long trip?

OP here — I recorded a short video and noted speed, temp, and whether it was in gear.

Fair, but a loaded-suspension check shows play that a wheels-hanging inspection misses.

Small add: capture when the 1970 Datsun 240Z does it — temp, speed, and whether it is in gear — before replacing parts.

I checked the easy stuff first on the 1970 Datsun 240Z and found one clue worth chasing before I book a shop.

If it were mine, I would want a real battery/charging test, not just resting voltage, before blaming a module.
