Parts keep getting corrupted - huge file size

I have a part which is causing me major issues. Recently it has caused Inventor to freeze up and use 100% of my available RAM trying open/save/update files, but never stops loading.
I deleted the part and remade it, which worked... temporarily. The same thing happened again, so I think it's more to do with how I'm using the part than the part itself being the root of the issue.
I will explain how I'm using this part. I'm not able to share the whole tree of models due to confidentiality.
- I have a master part model, with a few different solid bodies.
- I have derived a part from one of the solid bodies (this is the problem file).
- I have then used that part in an assembly which is the assembly which goes on my drawings.
- Then I have derived a part from that entire assembly to use for my FEA experiments to see how it performs. This lets me easily fill in any gaps with material, and modify the parts slightly in preparation for the FEA to run, which is why I don't just do FEA on the assembly file.
I have been going back and forth running the FEA and then modifying the master part, updating the FEA model and running it again. This works for a few times but then for some reason it gets corrupted at some point, and as you can see from the attached part file, its file size is huge (550 times the size of the other parts I made). In fact, it's nearly at the limit for what this forum allows to upload (55 MB out of the 71 MB allowance).
I have sunk a lot of hours into this to no avail other than identifying that the part file size seems to be part of the issue. My suspicion is that maybe when updating or saving the FEA file, it modifies and corrupts the part(??)
Is anyone able to find what all of the storage is being used for - why is the part so unnecessarily large?
Is there a way to avoid this happening?
Thanks!
