Try printing at a lower speed. It could be you are asking too much from your bed-flinger printer.

This post looks a bit old. I am using and Ender 3 V2. I am experiencing this same issue. Was a solution ever found? I am starting to suspect software or firmware issues rather than hardware or printer issues.
If anyone else has seen this or knows of a cause and solution please advise.
Have you tried any of the suggestions in the two posts above yours?
I would say: start by marking all pulleys, belts, etc. with a marker. And see if they move relatively to each other.
Or otherwise, check if the driver-chips don't get too hot (e.g. cooling fan not working, vents blocked), so they do a temporary thermal shutdown, until temp drops again to a safe level.
Check if the cables to the steppers are okay, no bad contacts?
These are the first things that come to mind, but I don't know your printer, so there could be other issues.
