Basic Spinning Top Prints Fail in Same Location
To me, it looks like your G-code induces an incomplete layer of support on the still standing piece, which later down leads to the print failing.

Re-slice the whole thing.

As a matter of fact, I would cut the model in its widest place and print both with the large face flat on the surface and glue the two pieces together after printing. That way I can achieve:


no need for support material
maximum adhesion
no surface problems on the transition from the support to the print
