Hello there, first time fro me I encountered this.
I run V1.03, did a previous flight of more of 3hours with no issue.
After having start back MSFS, on another flight, did have that after obtaining LOC* during an ILS interception. Was about at 4000ft, 220kn.
Avionics and engines were on during the fall. I didn't have time to notice the fuel or any other things (I wasn't aware of this topic).
I run a Ryzen 7 5800X with a 1080.
I did flown maybe 20 flights without any issue.
If it can helps.
