My car shutoff while driving but it started backup after a few minutes and had to turn the air off if I turn on the air it shuts off, I scanned the car but no codes.

This sounds like the fuel pump or crankshaft angle sensor is bad, when the engine stalls can you turn the key off, then back on again to see if you hear the fuel pump in the tank run for about 5 seconds? If not, I would change the fuel pump out.
