The fact that a power reset solves the problem points to the software. Something is getting out of sorts (bad data in a table/array somewhere) and the cycling of power forces everything back to startup/default mode. This could point to any number for problems with the circuit board(s), but could also be related to issues such as grounding or intermittant shorts in the sensor/input feeds. My first guess would be a bad solder joint on the board. The vibration of an airplane is a tough environment for electronic boards. It could also point to problems with your hall / VR sensor (not sure what your system uses). If the pulses are not clear to the logic controller, the unit can become confused. However, I would expect much more severe problems not just a limited timing drift.
