1 year ago I think you should post this on the main Marlin Firmware issues. if you can try using a different firmware, or a known good firmware file, maybe video record the issue, give as much details as possible.
I had an issue when I was swapping my stepper motor with an aftermarket one. it started like grinding and stuttering, just all around not good. I ended up swapping the two middle wires of the connector and that fixed that issue, which is almost sounding like whats going on with yours.
i would suggest try entering the gcode commands manually like via Pronterface. cura can do this also if the computer is plug into the printer.

Did you test with a precompiled firmware?
Yes, and the problem still exists.
Bug Description
When printing a large print with UBL with the following in my start gcode: G29 A ; Activate UBL bed leveling G29 L0 ; Load mesh from slot 0 G29 J ; Probe 3 points on the bed and tilt mesh accordingly
My whole printer keeps freezing for approx 1 second then continues to print for 1 second in a loop for around 30 seconds then the printer starts running smoothly again, it does the same again when the head reaches the same point on the next go around.
I'm slicing using Cura 5.3
This problem stops if I take that gcode out of the start gcode.
