Sorry but to not see the mention of Builtin Space Bar.

Find an Apple Authorized Service Provider or Visit a Genius at an Apple Store

This appears to a Hardware issue which only they can determine and or Evaluate the Computer

The accessibility keyboard is not enabled. In answer to Luis, I don’t know what the keyboard viewer is. This does not seem to be a hardware (mechanical) issue, because after restart it will work fine for months before doing it again.

The Keyboard Viewer lets you view the layout of keys, and also use your mouse if need be.

You can access it from the menu bar:

1) In System Preferences->Keyboard->Input Sources, turn on "Show Input menu in menu bar".

2) Choose "Show Keyboard Viewer":

Clicking the space in the Keyboard Viewer should in principle be equivalent to pressing the actual space key on your keyboard.

I have never had a space bar intermittently fail to function.

Make sure that Full Keyboard Access in your Accessibility preferences is turned OFF. Seems unlikely to be your issue, but that can cause space bar problems in certain circumstances.

When this happens, does the space bar in the Keyboard Viewer work, or does it fail also?

What is the user expecting the Space key to perform ?

Is this the Space Bar on the builtin keyboard ?

A swollen battery might cause keyboard malfunction. Or maybe dirt in the keyboard.
