Check for build up of lint and dust on the rubber of the activator cam roller, tension of the hold-off spring, if it happens on a flat section check nothing is pressing onto the top of the skate cover and that the nodder is clear of the cover also.
Over time the brake can become worn where it sits around the roller shaft, you’ll feel side to side movement if you give it a try, once in a blue moon that movement is enough for it get out of alignment to a point where it grips the roller shaft and activates.
Don’t know if Powerdrive are still carry spares, other than that if you don’t have a spare skate then the only real option you have is to keep resetting or sell them a new lift.
It may be that if you can source a slightly stronger hold off spring that may help a little, but I’d be very wary to do any sort of alteration to the osg.
Think it may be time to upgrade or at least prepare the ground
