Maybe you have intermittent electrical noise being generated blocking/stepping on the periodic rf packets?
In my case I thinks it’s actually more to do with temperature and the sensor/programming itself. Though I do get the occassional “out of no where” light which is likely a brief disconnect as you suggest, where it almost invariably comes on is when I drive on the highway for more than a half hour in early hours (pre 6AM) or similaryly in the rain.
So I think it’s relatively cooler road and ambient air compared to what it would be otherwise. I get same deal winter/summer.
