The more I read, the more I suspect that G43 is the problem.

i don't know which file work which not but i see 2 different
1. nc files the z top its 0.3937 while in tap file its 0.2
2. tap file you have in each time go to z the command S5903 i don't know what is this mean?
3. nc file height correction line its"G43 H103" while in tap its "G43 Z0.6 H1" why this z in the line?
from yours post sound like its some thing wrong with the pp in Fusion 360
try send sample of small nc file that work good and one sample that make that error
try both will be with same tool and same cuting depth ,so we can try help here
Are you talking about 3D cutting when the machine looses position, if so it could be that the motor tuning on the Z axis needs slowing down or the accel/decel needs upping to stop it loosing position.
