after resuming playing a radio station, it almost always stops after a few seconds

Using Squeeze Player with Orange Squeeze on an HTC Desire Z and against my own Windows-based server, almost after every time I've choosen to stop the playing and then starts it again it plays for 2-60 seconds before it stops, and I then have to manually restart it. Anyone having had the same problem? It seems like it's playing until some buffer's empty and then it stops. But it doesn't do this all the time, maybe 9 times out of 10 I have to restart it manually.
