I went through BIOS settings and could not find anything related to power loss. I did find the option where server is configured to dynamically operate in low power mode (but this is probably CPU related) and ASR (Auto System Recovery) was turned off.
So far nothing else jumped at me out of ordinary.

this looks like a bios configuration issue. Take look if you can find
anything "power loss" related in bios and change it from "off" to "last
state" or "on". I don't recall what it was called exaclty on the
proliant bios or where you can find that option in bios setup...
Hope this helps.
OT: You should also make usage of the iLO management devices in this
boxes, they are rock solid fencing devices and react faster than the
apc-power switches (we use DL360s and APC PDUs as fallback fencing
