Sounds like a corroded Power/Ground or signal wire to the sensors. Unplugging and Reconnecting most likely wont do anything. Any accident damage in the past at all? Months, years ago. It usually takes a while. A little Knick in wiring harness will take some time to corrode and some fresh snow/salt and corrosion could finally cause the wire to break. This is probably gonna require a little bit of time and a multimeter to diagnose. Not hard little bit annoying

Thank you for your time

Every time I disconnect a connector, I apply a smidge of the this stuff.

It is warm summer at my place. No rain or snow, nor accident and I got to exactly same situation and problem. At first I thought it is associated to brakes but after my testing on parking lot it seams to be related to decelerating to low speed. Please, if you resolved the problem let us know what was it.
