FrSky Telemetry Issue (FlightDeck)

I did an 8 minute automated mission flight and every went well. The second time that I did it, everything was the same. This time, RSSI dropped to 85dbi only once, about 3 minutes into the mission I started hearing multiple “sensor loss” and FlightDeck started to update less frequently. Upon landing and re-starting the radio, it wouldn’t connect to FlightDeck any longer.

Could this be the Cube being overloaded? I checked PM > Load, values range from 450 - 501 (is that 45%-50% load?). I just de-selected PID and Compass logging and load came down to about 400.

Has anyone had similar issues? Thanks!
