Ipod Classic randomly decides to stop/skip song/podcast

So my Ipod Classic 120 just randomly decides that the what it is playing is over and skips to the next song. This is extra annoying when listening to a 2 hour podcast and having to fast forward to where it was. Doing some quick searches I haven’t seen this problem mentioned elsewhere, has anyone here ever seen thins? It also does this even if the Ipod controls are locked. Suppose I’ll have to open a case with apple, it’s rather annoying.
