I am surmising that if major systems can't communicate, the DDE is programmed to shut down the motor to avoid bigger problems.
There could be a plethora of reasons for this and CAS module could be one of them. The bit that is troubling me, why is the AHM reporting 10.5 Volts? At such a low voltage I believe comms errors will start to appear.

From what was diagnosed, it seems the CAS was continually communicating with the DDE (when it shouldn't be). After a long drive, the DDE must be shutting itself down. I'll find out soon enough if it was the CAS module. I've been carrying my laptop and OBD2 cable with me in case it happens again.
Trailer module is on my list of things to investigate next. I haven't used to tow attachment yet as I'm waiting for a 13 pin to 7 pin round adapter to arrive to test the trailer lights.
