Toyota Repair: Land Cruiser stalling, mass air flow sensor, mass air flow

Question
I have a problem with my 91 L.C.;It runs about 10 minutes and then shuts down abruptly. I replaced the fuel pump and filter,mass air flow sensor and temp sensor;no difference.No check engine light.I would replace the fuel pump relay if I knew where it was or if bit has one. NAPA does'nt have it.Got any ideas? Thanks,Tom

Answer
The fuel pump relay also called the circuit opening relay is located inside under the left kick panel on a small junction block' it should be the relay closest to the bottom of this relay block, I would recommend replacing the EFI main relay located under the hood in the relay/fuse block as well.
