Ground wire is connected to a good ground, as verified by checking resistance to the negative terminal of my sub amplifier (<0.5 ohms).
Next step is to direct connect the fuel pump connector to the battery momentarily to determine if it's the power circuit to the pump or the wiring internal to the fuel tank.

I had a similar problem come up with my pump. Ended up being a ground that came loose in the basket assembly. The weight of the plastic connector that has the dust boot supplied by Aeromotive was putting slight constant pressure downwards in the wiring going to the underside of the hat, and the ground wire fitting got just loose enough for a poor connection.

When I out it together initially I'd wrapped the wiring up nicely and ziptied it to this OCD thought it looked nice and clean, but that ended up being the cause of the problem. I put a new connector on and left the wiring loose so nothing had any weight at all on it. Looked sloppy but out it all back together and worked like a charm.

Symptoms were similar to what you're describing.
