Sudden jerking or loss of power on highway

I drive a 2012 DSG, stock, with 17" snow tires. I was driving home yesterday afternoon in bad weather (snow) and every few minutes the car kept suddenly losing power for a fraction of a second, then it would kick back in. As if it suddenly slowed down and then sped back up. I was driving at around 60mph, and the problem only happened on the highway. Once I got onto surface roads it was fine. It happened both with and without cruise-control.

It only happened yesterday afternoon. Not yesterday morning, and not today in the morning. Also, no warning lights on the dash, and no funny sounds.

I called the dealer, they said that they would need to replicate it or see a light on the dash. Maybe I was slipping on ice. Is it possible that this was the traction control (or stability control or ASR) kicking in? I didn't see that "anti-skid" light on the dash. Does the car simply de-power when you hit a slippery patch at speed?

did the RPM drop? Did the car actually lost all electrical power and turned back on?

Thanks for the reply.

It didn't lose any electrical power. It just felt as if I had suddenly slowed and then accelerated hard. Or as if I had suddenly downshifted hard, or shifted down and then back up again. I wasn't watching the tachometer. Like I said, the roads were bad so I had to keep an eye on the road.

I was driving in worse conditions last week and I didn't experience this, but I was on surface roads going 40, rather than 60 on the highway.
