Twice in the last week, my computer has logged out when it seems overworked. Why?

I'm doing a lot of editing with FCP X and occasionally it seems like the system gets overtaxed. I've gotten the spinning wheel while the screen freezes (although I'll keep hearing what I was watching). Then, after a short wait, I get logged out. It goes to the log-in screen when I boot up. What is this? I don't get a message about a kernel panic but it seems in that vein. Thoughts? Do I need to do something different to my computer?

I didn't understand that comment. How do I do that default? Will it harn my computer to overwrite the heat log out?

I'm still having this problem. It happened twice today. I did maintenance and cleared space. i checked the log and found this: MacOS error: -2147409654. thoughts?

does this happen when the battery is reaching low % left ?

Nope. I'm plugged in and at 100%. Also, my Mac temperature is 55 degrees so I dont think it's that.
