[Corrupted Gcode with long prints when using USB on Ultimaker 3 Extended]

I have run into an issue when printing large products on our Ultimaker 3 extended. I have done some troubleshooting myself but I cannot find the cause.

I generate the gcode file with Cura 2.5.0 (roughly 170mb). as a check I load the file in Simplify3D all looks well.

I copy the file over to a USB stick with more than enough memory on it, then load the file from the stick into Simplify3D to check again, all is well.

I remove the USB stick from my PC (even using safely remove hardware in windows) start the print and somewhere during the 20+ hours the printer stops, and claims that the job is finished even though it is not.

What I found so far is that once I try to open the gcode again (load from the USB stick) Cura refuses to open it gving a "failed to read Gcode" error, and simplify3D shows the model as it has been printed (cut off). I even delved into the gcode by opening in notepad and indeed it seems as if the second part/half of the print is no longer present in the Gcode.

I have tried several USB sticks but I run into the same issue, it only happens with files > 100mb

Has anyone else run into this issue? What can I do to solve this, as it has cost my quite abit of filament on sailed prints so far.
