The engine is misfring on one or more cylinders at idle and this is causing the VSC indicator lights to be turned on, the stalling at idle and lack of power.
Water has gained entry to the ignition coils and spark plugs and this would result in misfiring. You need to remove the spark plugs to dry them out as presence of water is causing the misfiring.
