I've had the A310 for a good few months now and have had no issues with it whatsoever until recently.
So the problem is that after taking off on a flight, I get the bird up to cruise and everything is fine but then after a short while the aircraft disengages the autopilot and goes absolutely nuts with a hard bank to the left or right and loses altitude rapidly. Also on one occasion she lost all power and the screens went to black. Before anyone says it, no it's not an icing issue as this has happened on my last 4 flights and each time the anti ice was switched on. This problem has only started happening over the past week and I've re-installed the aircraft but that didn't solve the problem so I'm now stumped as to what is causing this strange behaviour.
Can anyone shed any light on this and possibly give a solution as short of uninstalling XPlane I really don't know what else to do.
I've attached the Log file if this will help anyone identify the problem.
