Car shuts down while driving

I have a 1999 park avenue.
When it gets up to operating temp. The car will shut off. It will start when cold and run fine until it gets up to operating temp, I have put in a new fuel pump replaced all the plugs, and the fuel pressure regulator,
Cleaned the idle air control valve, it is moving fine and is set to 11/2 inches, when you try to start it will hit and die right after it hits, no lights or on.

Fulr press. Is goden

Car dieing off and sputtering. I recently put fuel injector cleaner and premium fuel in car but it continues to sputter and die off.
