There is a difference between your screen locking (where you enter your password to unlock it) and logging out (which quits all open applications, though they can be reopened on log in). Check System Settings > Privacy & Security > Advanced and if the automatic log out after inactivity setting is on, turn it off.

OK, the additional information is helpful. You’re not being logged out, your Mac is experiencing a crash caused by the windowserver process.

That is often caused by an incompatible third-party application for extension. See if the problem is present when you boot in safe mode, which disables 3rd party extensions and performs some system cleanup.
