Engine Shut Off Without Warning problems of the 2011 Subaru Legacy

I was coming to a red light slowing down from 15 mph while applying the breaks, the car acts like something is grabing & it shuts down the motor. The car was not cold it was warmed up & drove about 28 miles before doing this. The skid light came on. It was a dry road. This car has done it several times. I have searched this on the internet & have seen others saying the same thing has happened with their Subaru. Its scary to think this might happen to me on one of our slick roads going off a hill. I have not had it checked out yet do to the holiday season. It does not happen every time I drive it. I have noticed while applying the breaks when it starts feeling like the rotors are grabbing if you ease off just a little and then apply again the car will not shut off it will stay running. I have shut off the skid protection and drove it & still it will do this and the skid light will show up. On the internet it says it could be the icv valve. But im not sure that has anything to do with the skid protection. I bought the car this summer & I had the dealer ship to put new breaks and rotors on it before I bought it. Had no trouble at all with this untill last month. I just had the oil and filter changed this week. There are no service lights staying lit. & it still does this. I will be getting this checked out. A guy mentioned that it could be the transmition. This car is an automatic & does have the manual transmission shifters on the steering wheel. The car was in the automatic mode when this happened it is not drove in the manual side. Im thinking I should try driving in the manual side to see if it will do this. Ive had no complaints with any of my other Subarus weve owned. I have never had this problem with them. However I have never owned one with the skid protection or in the 2000 model until this one.
