Why would a Datsun 280Z stall then die while driving?

Answer 1

Answerive had a few 260 z 2+2 and c210 skylines with the L series engines in them and a few times i have driven down the road and they have died on me at any speed here is a small check list of things to check, points,gap,plugs,timing and carby settings all play a crucial roll and lets not forget altenator, compression and valve clearances,head gasket just to name a few the L series motors can be tricky to work out but when you go over them a few times you will be able to fix it each time and you will be happy for doing it your self i say buy a book on the L series 6 and you can fix it with ease.

There were no 280z's with points or carbs. A more likely culprit would be a bad ground or clogged fuel filter.

If the car shuts off like you turned the key off, it maybe an electrical problem. Cleaning the fusible link connections (make them shine with Brasso) sometimes fixes this issue.
