Hi

Glad you saved the plane.... I also own a F18 and this is not an easy task.

Did you noticed a white smoke coming out of the turbine when it stopped? Was the UAT full after landing?

Wren uses Gaspar fadec, if it was a fail safe shut-off, the message should not be "normal shutdown". I used to had a Merlin 90 (same fadec), but don't recall this.

From your statement, you don't mention anything about the fuel circuit, so it is hard to say.

Once a plane flying with a Merlin90 crashed because the electric cable of the fuel valve was broken. The fuel valve is NC.

Maybe valves are the same as Merlin as well, because Wren does not manufactures valves. If the valve cable is cut in flight, the message should be "normal shutdown"

Among other thisngs, check your fuel valve....
