'elastic' drivetrain

The power transfer on my P7 is becoming more and more sluggish under acceleration, especially on the flat and climbing, to the point where it feels like my chain is elastic and it takes a while for it to get going.

The current set up is: RaceFace Cranks & Chainrings, SRAM chain, SLX rear mech, shimano cassette, shimano 525 hub... wheels have mavic XM317 rims and Maxxis Advantage 2.25 tyres....

The only weak link I can see is the hub - had the bike less than 8 months and had to strip it down twice already - but it has recently been serviced and the problem persists. I will be upgrading to a Hope Pro 2 in the new year.

It has been suggested that the tyres maybe contributing but I havent heard a bad thing said about the Advantage's.

Does anybody have any suggestions or had any similar issues? And before anyone says it, no it's not fitness related!!!
