iPad 2 stops playing music.

I've searched and found quite a few threads along this line but none specifically for the iPad with my exact problem and none of the other solutions worked for me so here goes:

Ever since I upgraded to iOS5 (now 5.0.1), while using the Music app on "shuffle" my iPad it will play 2 or 3 songs and then just stop. The "play" button still shows that it is playing but there is no music and the slider showing song progress is not moving. If I press the play/pause button nothing happens except the button changes from the play icon to the pause icon and back. I have to either quit the app or press the shuffle button again to get the music playing and then it will switch to a new song while the display shows the previous song and the progress slider moves along.

Thoughts?

TIA
