This problem is reported on INAV GitHub pages every few weeks: when DSHOT is used, motors stop after 10 seconds or so. The cause is very simple: when 4kHz or 8kHz mode is used, and magnetometer is enabled, I2C bus processing might take so much time, that it messes up DSHOT processing and causes ESCs to stop the motors. The solution is quite simple: either overclock I2C with CLI command set i2c_speed = 800khz or use 2kHz mode. And everything will be just fine! Oh, Telemetry over SoftwareSerial can also cause similar problems. Advice: do not use Software Serial!
