Most balls that "roll out" do so because they encounter friction too soon. Try moving slightly inside but swing the ball out to the dry. If that doesn't help, then adjust the cover depending on where you'd like to use it.
If you'd like to stay on the dry, then a little polish will probably keep it from rolling out. If you have some Bean's Secret Sauce, I'd recommend it. If you'd like to play a little deeper, then try it around 2000 abralon first, and gradually go duller if needed.
Don't do much until you use it again, though, since lane conditions are always changing. It's hard to pinpoint what is best for you because I can't see you bowl, etc.
