Complete electrical system shutdown. Occurred while driving and when trying to start. No electrical power whatsoever. Completely dead. Waited several minutes. Still dead. Waited another 10 minutes. Started. It is occurred three times in 48 hours. I hear a clicking sound from behind the light end of the dashboard. Similar to the sound of a starter when not sufficient cranking power to turn over. No warning on display. No advisory on display of what occurred.
