That is my guess as well, based on the information from the seminar. As I
understand it, the G1000 would disable (red "X") the readout of any
component with an unresolvable conflict. Since the aux tank was
"refilling" the main fuel tanks via the overflow return, it wouldn't be
long before the flight computer data would be in conflict with the fuel
level sensor and therefore generate an unresolvable error. It should be
expected that both displays would show the same error condition.

I guess that would be based on the invalid presumption that the fuel
computer, time to empty, fuel flow, etc have any interaction with the
fuel level indicators. They don't. You tell the time-to-empty
computer how much fuel is onboard and it deducts based on current fuel
flow. If you don't refresh it's fuel on board at the beginning of a
flight you can get 0:00 minutes to empty with hours worth of fuel left
in the tanks.
