Having the same issue with a Matika plunge saw that is 2 months old,can be in the middle of a cut and the saw powers down as if you have stopped cutting but your finger is still on the trigger. Has happened a number of times and have sent it back to the suppliers repair shop and they can’t find anything wrong with it and have advised until them have a problem with it then they can’t do anything about it. They are returning the saw to me and advised that I take a video of me using the saw when the problem happens again( not sure how safe that is when you are working on your own)
