I am having this same stalling issue. I originally thought my sound system was pulling too many amps at idle causing it to stall out, but then it happened today with it off, it is always at a red light and I am able to start back up but it is frustrating because I usually don't notice it stall and im like wtf.
I am just going to let it go till spring I don't have a garage and there is no way I am working on this damn thing in the 10+ inches of snow.
