[Solved!]AP disengages itself--&gtcrash

maybe some assignments in fs are the same as in the fsp menu ? not the right course selected , programmed something wrong in the
FMC ? maybe too high from the glide slope (I had it a few times and then he activates the LOC\VOR button and you go automatic to
TO/GA) do you turn off the auto throttle ?

these are a few things I can think of
