Why does cura Keep cutting out slices of my model

You should have gotten the "Your model is not watertight and may not print correctly" warning when you opened that in Cura.  There are a lot of open seams.

The model on the left is your OBJ file and the model on the right has been repaired with MS 3D Builder.  Notice how you can see right inside your model.  That's about the most obvious open seam I've come across.




Here is the X-Ray view and Cura has highlighted the open seams of the OBJ model in red.



Here they are sliced.  You can see that the repair has eliminated that gap.



In the Cura Marketplace is a handy plugin called Mesh Tools.  Install it and restart Cura.  When you right click on a model the top menu item will be Mesh Tools and you can select "Check Mesh".  If it tells you the model isn't watertight you will know it needs repair.
