Car shuts off after car warms up, with P1212 and U1001 codes

My car shuts off by its self, it is not random at all, it is always after the car starts and idles for a few minutes, then shuts off.
From what I have done already:
•Changed both cams sensors.
•Changed crank sensor.
•Changed fuel pump.
Car still turns off at the same time after the car warms up.
The throttle body was disconnected once to cleaning but I have done all three relearns that is required after you disconnect it and still the same out come.

Some other things That I noticed, before the car shuts off.
Once the car starts and idles for a few minutes, the rpm gauge goes from 300 to 0, but the car still running, slip and VDC lights come on, then I hear the fuel pump cuts off. But the engine stays on running for a few seconds after the fuel pump cuts out.
