I was having the same issue on a Mini after installing Cura 3.2.27 and doing the firmware update that it notified me of. Gears and other random prints would would just stop mid print. Sometimes the prints would stop at the same place. Sometimes different places.
I downloaded Cura 3.2.30 from the link provided and did the firmware update that it notified me of. Seems to have solved the problem! I have only done one print after the update but so far so good.
Thanks for getting this issue solved
Edit: I forgot I also changed the com port communication speed to 128000 in the device manager as recommended in the thread describing the troubleshooting of this problem.
Edit 2: I printed a couple of gears that failed consistently with Cura 3.2.27. They printed no problem with 3.2.30.
