Hardware test are usually a cursory scan and will not find  
intermittent problems, which is what you have--it works for a while  
then quits. After all those new installs and no relief, I think you  
have a hardware problem somewhere, either on the logic board or the  
disk. A system can hang with a bad disk waiting for it to respond.  
The only other self-diagnosis you might try is to boot and run off a  
firewire disk. If you do so, make sure you unmount the internal disk,  
if it mounts on startup, to prevent any interference if the system  
should ever try to access it and gets caught waiting on it.
