Assuming a completely stock setup, the ECU can vary the power directly to the fuel pump (no relay), so it's possible the power electronics in it are going bad and causing it to do that.
But that sounds mechanical to me, almost like it's sucking in bits of rust or debris... Might not be a bad idea to pull the pump out and take a look at things on the sender and inside the tank.
A bit of a risky proposition since the sender is unobtainium and you break anything on it, it could be a problem.

Looks like it was a forum software update, but the theme didn't carry over.

I still check in here every day or so though...

If the value of the S12 goes over 100G I'm sure it will.

It's important to understand the way the fuel pump is wired. The ECU provides and lifts the ground, so that's why those above have grounded the pump directly to get around any ECU solder joint issues.

I also had a problem with the fuel pump grounding so try grounding the pump directly to the chassis.

I had similar problems some years ago. The fuelpump would just stop under heavier load and the engine died for a moment. It turned out a combination of problems, fuel tank was full of sandlike rust so I got the fuel tank refurbished and the inside epoxy coated and the fuel pump was also bad so I replaced that with a Deatschwerks pump.

I also had the ECU connection problem rednucleus described but I just connected the fuel pump ground wire directly to chassis so now the pump turns on with ignition. I have not messed with the ECU solder joints.

Hey Gar welcome to the forum. This used to be a busy place, excited to see a new format starting this week. My pumps (two now) have always had a steady hum, not like yours is doing. My 1st one had an intermittent cut out, changed it and no better. Found my ECU had random bad solder joints - touched them all up with a solder gun and no problems now for years.  Is yours original pump? How much fuel in the tank??
