I recorded to a card (I always record to a card). I had enough power.
It might also depend on the amount of data you are recording (cadence/speed/heart rate).
I don't have a lot of information about the issue. I've heard about it and had a problem at around 180 miles that appeared it might have been the same sort of issue (maybe, it wasn't!).
Part of the problem is that it's hard to duplicate.
I mentioned it as more of "there might be an issue that you need to be aware of".
