Mine was doing somthing similar and it was a bad spot in the mp3.
I got by it pressing the fast forward key repeatadly just as it was getting ready to start playing again.

That did it for me, I was able to get past the bad spot, skip to a different song & make a note of it so I could remove & fix it later.
