Looks like you just need to tighten your BB cups. Even the most minute bit of play can be felt under load at certain points in the pedal stroke.
EDIT: If it's a fairly recent purchase, BLB should just tighten them for you for free while-you-wait (best give the shop a call to say when you'll be dropping by).
