Quality Check PI has this (and many other checks):
Check EPUB Structure: Check oversize HTML files
Note: you can't set the size here (I think it uses the size from Calibre preferences)
60 KB is unusually small. 260KB is typical RMSDK (ADE)
are there inline images? That may cramp the available RAM.
I suspect you are running into (HiRes) Large Images, which cause my old (favorite) device to abend. I would run that check first
You can select the results and add a Bulk Tag for later considerations
