Are you absolutely sure the cable is slipping? Does it always move in the same direction? (Gets harder to pedal for traditional rear derailleur.) Never happens in index mode? Skipping on worn cogs with a newer chain can seem like a shifting problem especially if it's on the larger cogs and you're pedaling hard uphill. If the cassette is oldish, replacing it can narrow down the possibilities.
