Sometimes when I coast my freehub stops freewheeling and other times when I am off my bike and wheeling it around the crank turns. I have just cleaned the drivetrain really well and it is still doing it. I removed the freehub body from my power tap 2.4 SL and am wondering if there is supposed to be a washer that sits on top of the bearing?
Not sure if that is the source of the problem. If not, any other ideas?

I am no expert on powertap hubs, but not likely that this happens, or else you would be riding a fixed gear bike. Or, can you explain better?

You should be able fix this issue by cleaning out the freehub mech and any old, thick grease in there. Replace the old reehub mech/pawl grease with some type of fairly tenacious oil, or new but very thin grease. Then this should stop.
Sometimes when I stop pedaling the freehub will continue to spin instead of freewheeling.
That would be hard, because if it were still spinning, the cassette, the chain, your cranks, and your legs would still be moving, as they are all connected. Or what am I missing?
Sorry its late for me. The freehub continues to turn until there is no slack in the chain and the cage on the rear der is pulled all the wayforward.
Sounds like the freehub has lots of resistance, but if you cleaned it out and it is still happening, I’d contact the powertap folks and ask their advice.
Without knowing much, i’d also suggest to check your cassette.
There is a spacer/washer that can go on first before the cassette.
Some hubs it’s not needed and some it is.
I have one PT hub that needs two washers for it to spin freely.
I had the same problem with my PT Elite+ after it came back from a service. I found that the freehub was somewhat loose and when I torqued it to the correct spec, to would bind on the hub body. Backing off about 1/2 a turn made the problem go away.
I fixed it by making a 0.2mm shim that I placed between the shaft shoulder you see in your picture and the inner freehub bearing.
