I have looked at the code but have not seen anything that might cause it. I have made some changes that may help narrow it down or may even fix it if its due to a spurious MMBasic reset. (Which is the only think I can see which would clear the Program Memory and leave the firmware intact.) PC13 was implicated with the SDCard in the past so maybe something is triggered when writing your log file.
There are two things in the firmware.
1. An MMBasic Reset will report itself on the console at the restart after the reset so you know it has happened.
2. An MMBasic Reset will only be triggered during a Power Restart. Once MMBasic is running it will not trigger an MMBasic Reset no matter what conditions are placed on PC13.
This firmware requires a GND on PC13 to trigger the MMBasic Reset as before.
3.3V on PC13 will trigger a switch to the serial console, again only at a Power Restart.
