There seems to be no method to the madness of what my clients are calling a "kick-out bug" in the CMS.

They enter information for a page, select a different tab or to save, and they are told they have to log in again to access the page.

It occurs when editing any given page type, but not consistently.

The install is 2.3.3. I've looked though the forums and found a post where someone complains of this happening upon save for a forum post, but not the same way it's happening here.

Any ideas? Is this happening to anyone else?

Hi,
Could be that the session duration is somewhat short and times out on the server while the user is entering data. I have one hosting account where that happens on a regular basis. It might just help for them to just save now and again while composing content...
