Default No power to fuel pump relay under the hood

So my 1990 ls400 start dying out on me while driving it would shut off and I'd put it in neutral and start it back up again well that on worked a few times. After working on it I checked the fuel pump relay connecting wire, come to find out there was no electric current running through the harness connector that goes to FPR (Fuel Pump Relay) any ideas what can cause that??????
