All feeds time out after a certain amount of time so you just need to restart the one you want when this happens.
A better solution may be to use a standard media player instead.. Just open up the media player you want. Then select the corresponding player in the drop down menu ... Once you do that, you can then drag the feed play icon into the playlist window... Repeat that last step a couple times... This will ensure you wont miss out on the feed you want .because when the first one times out or gets reset on you, The second one will automatically begin playing. That way you will hear only the stream you want to listen to.
