As the title says. On climbs the motor starts to lose power and the way to "reset" it is to backpedal a stroke or two and the full power comes back. This happens in any boost mode, whether it's hot or cold weather and needs to be reset every half mile or so. Motor is 3 years old, has about 2000 miles of mostly gravel uphill and single trail downhill, nothing extreme. Doesn't seem to happen on flat riding, just when it needs constant input.

It's annoying as hell and I wonder if anyone has/had the same issue and if there is a fix?
