I used to get 41 records returned before it hangs and now I get 5. I haven't changed anything to the mapserver code directly. What could this possibly be related too? Memory errors?

Sounds very much like a memory issue and you could run after it for days 
like this.  If you're on Linux then you could install Valgrind 
(http://developer.kde.org/~sewardj/) and run your request in Valgrind at 
the command-line.  You'll be amazed by this tool, it should point you in 
the right direction in a few minutes.  If you're on Windows then you 
could try Purify from http://www.rational.com/
