Sudden turn off the engine

Today as i was driving the car’s engine turned off…it happened twice with medium to slow speed.

Obviously this could not have been any battery problems so upon my return i plugged VCDS.

The fault i found was in each bank the pretty standard warm up catalyst error due to my piggies (since i have not been able to flash the JHM tune) and a SAI insufficient flow on bank 2.

Could those faults have caused the car to shut down while on circulation?
