Itunes keeps stopping


I am using Itunes to stream music to my system through a airport express. It works fine except recently Itunes keeps stopping. I have to go into Itunes and click on play again. It is starting to do this every song and a half. It is beyond being able to listen to. I tryed to restart the system that does not work. I removed Itunes from my computer and reloaded the program and that did not work. It is very frustrating. Any suggestions?

My friend had these issues and I think he changed to a different "channel" for the wireless - something other than default. I don't remember all the things he tried. Although, if it just started happening, it may be something new.

Both OS and AE are current. No microwave being used at that time. Latest version of iTunes installed when problems started.
