Treadmill Run: Inaccurate 3 minute/mile pace!

I logged a treadmill run this morning and everything was fine till near the end when the watch suddenly began showing that I was running 3:20/mile instead of about a 9:00/mile that I was actually running. Any idea how/why this might have happened?

Details:

I was wearing the Fenix 5x watch on my wrist, and also wearing a foot pod and chest strap HRM.

I've done a number of treadmill runs, and never had anything like this happen.
