Have your ISP check to ensure the two fans at the back of
your RaQ are still running.

Get the RaQ connected to a terminal server at your ISP and 
log the output.  The console output may show the cause of
the reboots.

When the RaQ is online, transfer /var/log/messages to
another machine.  Once transferred, search the log for
reboots, then read back a bit to find out what triggered
it.  

Sometimes a server can crash without logging anything,
if this is the case, check fans, then RMA or swap memory, 
disk.

This diagnostic recipe largely applies to any unix server...
