1. Assign a name to your BeginStoryboard

   <BeginStoryboard x:Name="Move">
   

2. To pause, add this

   <EventTrigger RoutedEvent="MouseEnter">
        <PauseStoryboard BeginStoryboardName="Move"/>
   </EventTrigger>
   

3. To resume, add this

   <EventTrigger RoutedEvent="MouseLeave">
        <ResumeStoryboard BeginStoryboardName="Move"/>
   </EventTrigger>
