1) All avionics software implements internal isolation to prevent one
part of the system from taking down another part.

Except the G1000, apparently.

2) A faulty fuel reading cannot cause the system to reboot. In addition
to testing every possible faulty fuel value, I've tested every
combination of faulty sensor readings related to this thread and am
unable to get anything out of the ordinary to happen.

Since the system did reboot, there is obviously a combination of
circumstances that will cause it to reboot. It should never reboot.

3) When the system reboots due to a software error, a very obvious
message with a very obvious color is displayed on the screen prior to
the reboot. Was this seen? I have seen no mention of it.

How does an obvious message help?
