I performed 4 flights on this site a couple days ago
flight 1 - good trajectory output
flight 2 - average trajectory output
flight 3 - .gps file stops abruptly after 6 minutes recording (file services.log shows no traffic from receiver).
flight 4 - no .gps file recorded (zero information from receiver).
(between flight 3 and 4 I did not turn the unit OFF/ON at the field, I just stop recording, swap batteries and start recording again).

Did anyone faced this issue before?
The weird thing is that after this problem I did a new work with 5 flights and all went ok, no issues
