Ok from everything I can find and also your scenario. I can suggest that the issue is with either the throttle body or the throttle body wiring. I'm just shocked that there were no codes as when the service stability light comes on then a code is always stored. So that baffles me. The throttle valve is electronic and is also part of the stability system so the fact you had a running issue and a service message tells me the issue lies in the throttle body. The most common things we see at the shops are failed throttle body internal electronics or the connector to the throttle body. The gad pedals are also a issue but they would not cause a running fault. Now the other possibility is some bad fuel went through the system and you will never have this issue again. And once the key was cycled the engine ran fine so there were no chances for it to store a code. Those are the only two scenarios I can see happening. So if this happens again I would drop off at the dealer and tell them to keep driving with the scan tool attached to catch the issue in the act. OR if the issue happens when you drive it do not turn the key off of it will stay running and bring it to the dealer asap to have them see the live data.
