Hi Ilsan,

From the GDT, what were the causes of each flameouts? Were you able to notice this?

In addition to the EGT probe position (inserted not more than 2mm), when was the last time the engine receive auto high speed calibration? While the engine is running (approx 50%), go to the third page menu on the GDT and perform the auto speed calibration. Fuel pump and fuel plumbing conditions may have changed with time so recalibration once every 10-15 flight should be a good practice.

My suggestions:

1. Check EGT propbe setting
2. Check fuel tank/lines
2. Make sure that your TEMS battery pack is fully charged
3. Start engine and Recalibrate with auto high speed as described in the manual
4. Set the Min/Max rpm
5. Observe fuel pump voltage at full power, the voltage should not be more than 6V (excessive voltage indicates blockage in the fuel system)
