Audi S6 owners have reported 2 problems related to engine shut off without warning (under the engine and engine cooling category). The most recently reported issues are listed below.
After driving the vehicle under normal driving conditions, I arrived at my destination and without any warning or dash lights the vehicle shut off roughly. Since it sounded weird, I tried starting the vehicle back up again. The engine would crank but wouldn't start. The vehicle was inspected by a Volkswagen dealership where it was determined one of the two turbochargers had failed. The passenger side turbine wheel was broken and the driver side turbo was showing signs of the turbine wheel catching the housing. Both turbos were replaced along with the turbo oil screen.

Engine shut down while on freeway at 60mph speed due to turbo failure. 60,000 miles on engine. Issue caused by oil pickup screen being clogged and starved the turbos from oil, thus resulted in failure and engine shut down.
