The actual problems have not been described, but the OP does show some good NEMA data (not that I validated that) and did say there is no problem logging the data "all day long" which suggests it's probably not serial buffering.It could be the serial setup and the serial port/module setting is backlogging data, I've seen this happen before in Python code.
Some solutions have been to force flush, the data before a read. But it's been many years now..
That's from reading your problem.of everything works but the data (GNSS nmea string) doesn't seem to be quite right when it comes to using it.
Maybe we will get a better account of the issues soon.
