just add more water! The engine will think it's doing something wrong NOT running on water haha.
Seriously though, try changing out the spark plugs or something, and if you're under warranty just bring it to the dealer, it might be that a coil pack went and it jsut happens to be a coincidence that it happened now. It's a common issue on xBs and it is covered under warranty.
