This was happening to me on a new build recently after I thought I'd done everything up tight, ridden it and tightened it again. It turned out the lockring was bottoming out before tightening up fully on the cog, allowing for a bit of slip when accelerating/braking. A 1mm spacer sorted it out nicely and it's now happy days. I have a spare one if you need it.
