Hello
Today was the first time I encountered this issue. All my former flights went smooth.
I was in Cruise between KBOS and KDEN at FL340.
Had a good amount of fuel remaining in all tanks. Unfortunately I didn't check the Fuel Temp or Fuel Lever Positions during the event.
I also was in 4x time compression.
IF it happens again, I'll check those values.
rgrds,
Benni
