I'm having a problem with fuel as well. Engine cuts out and the fuel pressure light comes on.
While losing altitude, I hit the fuel wobble until the low pressure light goes out, then did an engine restart and carried on with the mission.
This happened twice in the same mission, at about 20k altitude, but I was able to complete the mission and fly home, so lack of fuel was not the problem. Oil and rad temps were very low. How do I prevent this? Radiator only has two settings: Open and Auto (I was set to Auto).
Any advice would be appreciated. :)
