Default CTS stopped running

On a 2011 cts the caddy totally shut off, but after I came to complete stop, restarted w/o a problem. Any ideas from anyone, earlier rough idle while sitting in still with a/c on, thought it was shutting down.

I had an '03 STS that would shut off while driving and restart without issue. It was the CPU sensor.

Throttle body or harness. I would make sure there no carbon build up on bore and butterfly first. Go be auto parts store see if a DTC is stored.
