Are you sure that you are losing history rather than getting the history
for some interactive shell that you had open but didn't use?
AFAIK, by default, bash overwrites the history file on exit, i.e. the last
shell that terminates gets to write the history. When you shut down,
shells terminate in no well-defined order so that with
history-overwriting, the shell that wins the race to write history may
just be the wrong one.

Try putting

shopt -s histappend

into your /etc/profile and see if that fixes your problem. This will cause
bash to append to the history file rather than overwrite it, thereby
causing your history to store history from all shells, not just the one
terminated last.
