Nano shuts off unexpectedly
I just received my replacement Nano. Set everything up, have all the latest updates to iTunes etc., but when a song is playing, halfway through the Nano shuts off. when I press the wakeup button the screen lights displaying a pause/play button appears with the name of the interrupted song.I have checked all settings and cannot figure this out.
Any suggestions?
MacBookPro, Mac OS X (10.6.3), 2.4GHz
