My SPECULATION is the card is fast enough to write to but not fast enough to close one file, append the FAT and the open the next file and start writing.

I have seen certain older SD card adaptors having throughput way below what I would consider decent headroom and that would cause problems. Indeed I experienced something similar myself way back in 2009.
After testing, I then binned all the adaptors and also changed brands of SD card.
The over crank test I have described elsewhere should weed out any problems. A good modern card and adaptor combo will fill an SD card with over cranked footage at 50fps without complaining.
