I have replaced the fuel pump, the fuel filter, and still when I reach half a tank of gas my vehicle will stall and not start again. I do drive down a red dirt road and this accumulates on everything could this be causing my problem

Hi, thanks for the donation. How long since a tune-up? I'd still have to use a gage and check fuel pressure, when the problem occurs. Some of the national brand autostores used to loan out a fuel pressure gage. Right now, I don't care how full your gas tank is, I'd have to start with the basics. Are there any codes?

Assuming that your gauge is correct I would say you have a hole in the pickup hose in the pump assembly. Did you replace the whole assembly or just the pump itself?Let me know

Just to be more specific I bought the fuel pump as one piece took out the old one and put in the new one.

Have seen this many times, it sounds like there is a pinhole in the hose that goes from the strainer to thepump itself in the assembly, when the gas level gets below that hole the pump only sucks air, similair to what we once refered to as vapor lock. This is not an uncommon problen remove the pump assembly and replace the length of hose from the strainer up to the pump and I believe this will solve your problem. Let me know.
