It happened again.

I found 
https://userbase.kde.org/System_Settings/Startup_and_Shutdown#Session_Management

It states:
To manually save a session, you must first select the "Restore manually 
saved session" option and "Apply". Then, when you use the "KDE Menu" -> 
"Leave" you will find that you have a new option - "Save Session".

In DE there is a "Restore manually saved session" option in "TDE 
Components" -> "Session Manager", which I selected.

When I ended the session there was no "Save Session" option from the 
Lock/Logout Panel Applet but it's there in the start menu!

I'll give that a try...
