I just went through the same thing with my Pista. After repeated trips to the LBS for tightening, I finally found someone who figured out what the problem was. The original shop that did the build on the bike used a cheaper cog than what came with the bike . (I assume that was to keep the better cog??? or maybe just stupid..) anyway the cheaper cog was slightly thinner, and did not sit tight against the tightened lockring. LBS gave me a .5mm spacer ring to go on the hub before the cog, to take up space... Unfortunately once i pulled the cog, the hub was stripped!!!!! this was a free fix, and had i done it a day earlier i could have saved mu hub!!!
