One other thing about fuel. Don't let anyone run dry before switching on other pumps. It'll shutdown in flight or wherever you're at hopefully with enough altitude for a re-start. I know; I've hit the dirt many a time to learn a sequence.

Pull throttle back; switch off autopilot; fly the plane and glide with airspeed enough to not stall and ctrl/shift f4 then ctrl e. While the engines re-start gradually move throttle up back to gain airspeed then altitude if needed and continue with where or what you were doing.
