Player shuts off repeatedly

So, I formatted the player from the player’s menu.  I then reloaded some of the deleted files.  The player was connected to my PC for 30-45 minutes then went off.  Now, back to the same issue: it will not stay on long enough to even play a song.  I pronouce it dead :-(   Does Sandisk repair these or would it be better to just get a refurb?
