I've found that my Libre doesn't like to get a "gradual" power up or down for charge supply. If it doesn't get a near instantaneous stable 5V on the USB port and then an immediate drop to 0V to remove the power, it sometimes will lock up and require a reset, as described above.
I've seen this happen with the supplied charger if you first plug it into the Libre and then into the A.C., or remove the A.C. with the charger still pluged into the Libre. To avoid this I now always plug the charger into a live A.C. outlet and then next plug the mini-USB cable into the Libre. I also unplug the mini-USB connector from the Libre before removing the charger from the A.C. outlet.
Since using a solar panel directly connected to a 12V to USB adapter, without a buffer battery, could cause the voltage to drop below 5V whenever the Sun went behind a cloud, etc., it's possible that these lockups may occur.
