Stop button acts like an E-Stop in the respect that it is instant and no deceleration is used so you are very likely to lose position if the axis is in motion. The procedure when an axis is moving is to press Feed Hold first then if required press Stop after the motion has halted.
Your E-Stop problem could be a few things, is there any message in the ticker window when it happens? Brains may not always pick up an input if it is a very short input as Brains only work at 10Hz so if the signal is short duration it can easily fall in between scans.
If there is no message in the ticker I would disable the Brains and PoKeys and run without them to see if the problem is still present, if it is then you know its not them, if it is not then you know it is and either way will know where to start looking to see where the problem lies.
