Stalls out while driving. It will suddenly(and sometimes just for a sec and keeps going) seem like its not getting gas, turn its self off(all the lights on dash come on but engine is shut down).

I don't blame the mechanics! I lifted the hood on one, and closed it. Z cars are awesome, but they're their own special breed. Try googling z car specialists. They do exist, and they can get your baby back purring like a z does so well.

here a some things you could try think I had similar problem. check the O2 sensor and all vacuum lines. Try it with O2 sensor unpluged it will run rich but it wont stall.

I had the very same issue with mine, Checked several things out...all but the fuel filter. I replaced that and it seems to have corrected it.

I have the same problem on a 1988 Nissan 300ZX. I'm driving along and the engine dies abruptly as if I were to turn off the ignition switch and then turn it back on turns off turns on maybe a second maybe two seconds maybe three but it always restarts and it may immediately stall again or it may run for a while? Did you ever find the problem on your car that was causing this same symptom?
