and if you look at your fuel used indicators to the immediate right, you can see that only your Engine 1 is getting/using fuel and it looks like from only one tank.

Actually, I messed that part up. Engine 1 hasn't used any fuel (that's why the zeros). So, it looks to me like you've got two engines drinking from one tank only. Once that fuel is gone, that's why your engines stop turning.

Why that's happening, I can't tell. Maybe someone smarter than me can spot something in the pictures. I'd still try the ready for takeoff scenario and see what happens, and try it with crossbleeds closed and lit up just for the heck of it. But it doesn't look like engine one is getting fuel and only Tank 1 is supplying any to the other two. It looks like you've got everything configured properly so I dunno. Sorry. I'm sure there's a solution, though.
