Have you measured/checked the supply voltage?...when first turned on as well as during operation as it becomes "anemic"?? Not sure what your power source is, but this might provide an 'upstream' problem clue.

Well, I've narrowed it down a bit. No binding or anything like that. And the supply voltage is fine.

HOWEVER, if I measure the voltage on the circuit board leads to the coil when it tries to pump, it's barely getting anything. If I supply voltage directly to the circuit board leads to the coil, it pumps just fine. So, something on the circuit board is limiting the voltage being sent to the coil.
