Renault Duster 2020?

Renault Duster 2020 model, at stop lights, suddenly get a "change gear to neutral"message and the engine totally loses power. happened today at a bump where I slowed down to 13 km/h and got the neutral message and there was absolutely no power. putting it into neutral doesn't help. i switch the gear to park and press the engine start/stop button until the car starts again and then it works fine. pretty unnerving and kind of random. noticed it only happens at slow speeds. renault official garade/distributor yet to call me back.
