Flash error

The most likely answer is that the content provider isn't 100% reliable.  Streaming video across the internet is both technically hard and relatively expensive to do well.

Since other content providers work fine, it's not a Flash Player issue, and it sounds like Flash Player, your computer and your network are all fine.  I'd start reporting outages to the content provider to see if you can help them track it down...
