Last night the engines both cut out randomly and I couldn't get them restarted at any altitude, only could restart them when I was on the ground. Every thing was fine I had APU bleed air and fuel. Log didn't seem to say anything odd except for "event" on almost every line followed by a random 1 digit number. As a side note when I was on the ground doing the next flight both engines started randomly, is there like a copilot AI I'm unaware of or something?
