300ZX Turbo runs for 60 seconds then dies.

[g.otero]

I have a 300zx turbo that will start right up on the first crank and it will run perfectly for exactly 60 seconds then it will die. If I tap the key to start it again it will fire right back up idle smoothly and then again after 60 seconds it will die.......It has a fresh tune-up plugs, wires, fuel filter, air filter, and no vacuum leaks? I just don’t know anymore. please help

Welcome to Nico!I would tend to think the MAS, or maybe the fuel pump relay, sounds like maybe the pump comes on when you fire up but goes off afterwords and just runs off the fuel in the rail for a few seconds
