Ok sorry it has a electronic ignition

It Will Have to sit 5-10 minutes before restart

SteveJ will probably figure it out.

 

I forgot (again) that 1974 should have stock Nissan electronic ignition.  The introduction of electronic to the Z's.  Always good to confirm though, people do swap.  Is it the stock unit, down by the fuse box, or aftermarket?

 

Just trying to help.  It's the details that will solve the problem.  Pictures would be great.

Is (or was) the car an automatic? The reason I ask is that the autos had two pickups in the distributor and a different ignition module that accepted signals from both pickups. In the auto cars, it switched from one pickup to the other when the engine warmed up some. Maybe when your engine warms up a little it switches to the other pickup and for some reason you lose spark?

 

If it's a manual car, maybe a PO put in the ignition module from an auto car? Just tossing out ideas that could let the car run OK for a short time and then have it die like you turned the key off.

 

I'm with SteveJ. I would also be surprised if it's a fuel delivery issue. I'm thinking something electrical... If it's fuel, it wouldn't die so abruptly. You'd sputter and cough as your float bowls were sucked dry. And it wouldn't restart smoothly either. You'd have to crank a bunch of times until you had enough fuel back in the bowls to keep it running.
