Carlos,

As long as you have correctly programmed the ECU with your TX then it should say Failsafe following a failsafe shutdown. What you are showing is a flameout indication.

You can test the Failsafe function by turning off the Tx once the engine is running to confirm that it shuts down correctly and with the correct message.

All my unexplained flameouts were due to filter restrictions, with a secondary indication of elevated Pw at full throttle. I'm running 2 Merlin 140XBLs (brushless pumps) so the Pw value is different from the older brushed pump motors, but the issue and indication is the same.

I have back-flushed my fuel system with a gallon of fuel as a temporary work-around prior to replacing the MAP Air Trap with integral filter.
