My car dies randomly and without warning. As though someone shut it off with the key. I have had it in several shops and no one can figure it out. After it dies it will start back up really easy most of the time. On rare occasions it has taken 5-10 attempts. I have changed the fuel pump, camshaft position sensor, EGR valve, MAP sensor and had the coils and module tested. Any other suggestions?

PLEASE HELP

When it dies, is it at idle or whenever?
Have you checked for DTCs and make sure the sensors inputs are within range?
I would also check for a vacuum leak and make sure the fuel injectors are not dirty.
You could also try to clean your IAC valve and the throttle body if it's dirty.
Check your CPS sensor.

Finally, have you made sure you have a good spark?
Check your spark plugs, wires, loose connectors etc.

Unplug the mass air flow sensor, and I bet it will start right up.
