Automatic shut down problem

I am a computer teacher in a lab with 30 Mac 475's connected with an
Ethernet network. The machines have 8 MB RAM, System 7.5, and I'm using
At Ease for Workgroups for system security. Most student work is done
using ClarisWorks 3.0 and Simple Text. Each half of the room is on its
own 20 Amp circuit, and each pair of computers is plugged into its own
surge protector/power strip. The problem I'm having is that I have two
specfic computers that do a shutdown/restart automatically while students
are working. It has happened simultaneously several times (I know it is
not the students because it has happened in different classes and it is
at the exact same instant on both). One other machine did the same but
it was only an isolated incident. Does this sound like an electrical
problem or do I have hardware or software problems?? Any insight or
words of advice would be appreciated. Thank you in advance.
