Is it consistently the same spots in the wheel? if so - then I'd say it's the box. If it's random, it can be either, but if your pump is whining or hissing a lot - I'd say it's that then.

Sounds like the pump is bad. Either that or something is stuck in the lines or the control valve that is built into the pump. Keep us informed.
