Today I was doing a flight from VIDP-EDDF, in a 788. Around 1 hour and 26 minutes in, my speed started decreasing to M .71. Farther into the flight, the autopilot disengaged and sent the aircraft into a crash. I went out for lunch, but supervised until cruise to make sure it would not stall out. No one was in my house at the time of the crash and I suspect a bug. I would appreciate it if you guys could take a look and determine if the crash was my fault or a bug.
