In owners' own words
I was driving in a parking garage so my speed was about 5-10MPH when the whole system shut down. The car stopped moving and all of the system warnings popped off (ABS, stabiltrack,engine).
Code P0430 cam or crank shaft position censor. Timing chain issue caused by manufacture defection. Rear driver side passenger seat belt not working properly.
Shortly after the purchase of the vehicle it started shutting off while in motion. This happens unexpectedly, and mostly when slowing down for a stop light or to reduce speed.

Recalls for the 2008 Cadillac CTS: 2
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. It is possible for the heated washer module to ignite and a fire may occur.
