I have a 1982 280ZX non turbo. My car cuts off after 15 minutes of running. If i wait 15 minutes it starts right up and runs like a champ again.

I've changed distributors, I've changes Ignition coil I've gotten new cables but nothing seems to work. I've recently tried changing the fuel pump since no gas it getting to the engine during this time. I've run out of options. Again it run greats but cuts off after 15 minutes or so.

May check the fuel relay,but i think you may need to check that new fuel pump,some time,s you get a bad aftermarket one right off the bat.
Did you change the fuel filter? Did you check for spark at the engine? Also take a look at the check valve at the fuel pump. If they get stuck closed then you won't get any fuel.
I had that issue and it was the Cylinder Head Temperature Sensor, The connector was super corroded. I changed the CHTS and cleaned the connector. When the CHTS goes bad it dumps fuel into the engine until the sparkplugs are too wet to fire. If you jumper the CHTS connector by putting a wire into each end you trick the engine into thinking its good and warmed up, and it stops dumping extra fuel into the engine.
