Machine suddenly slowing feedrates

I swear I saw this reported elsewhere so feel free to insult my search skills and point me to an existing thread if you know of one. I had a weird one today, I was cutting a project and the first few steps were fine. Then I noticed it was moving super slowly, and I assumed I messed up a setting but let it go through a few more steps. Even when it was on a step I verified was set at 70ipm feedrate it was moving absurdly slow. Took a short video of the feedrate.
