2002 Escort zx2 no power

I have to start by saying that this vehicle is used as a professional rally racing car, and for the most part has done a GREAT job. However, the above issues are EXACTLY the same. I can push the gas down up to half way, and the car will do just fine the entire time. But when I give it a bit more 'go-juice' the car begins to buck and eventually looses all power. Take my foot off the gas and then reapply it half way, no issue. I have replaced the TPS with so effect. There are no conclusive OBD II codes being produced. NOW, I will say that before, it seemed to correspond to the level of gas in the fuel tank. Any help on this issue?

The fuel pump and fuel tank have gone bad. Pull the rear seat which attaches with two clips in the front, use a flat head and hammer to remove the fuel pump locking ring and pull the pump by unclipping two white tabs on either side. It’s tricky to get out but just be patient and wiggle it around in all sorts of ways and you’ll get it. I’m certain what you’ll find is a gas tank that’s full of rust and clogging up the pump. The reason it’s better with more gas in the tank is rust that’s clogging up the pump spread around more in the gas thus making it easier for the pump to work. You can either clean the rust out of the tank using various rust dissolving chemicals. Vinegar works well but takes some time. Don’t use muriatic acid! Or B: just replace the tank. I personally would opt for B but if budget is a concern, you could get a couple more years of life out of the tank by cleaning and getting rid of the rust. Replace the fuel pump, don’t bother trying to clean it. Put a new fuel filter in and it's good to go.

With only 54,000 miles I bet the car sat for a long time and when cars sit, gas soaks up moisture out of the air and eventually the gas soaks up so much moisture it can’t hold on to it anymore and it falls out of solution. Straight up water in your gas tank.
