Fuel Dies when I go down hill or take foot off of accelerator to slow down.

Since it happens when the fuel is lower, and the fuel filter helped, you may want to take a look inside the tank. Hot and humid combined with 18 years of use and a corrosive liquid can do a lot to the inside of a fuel tank. You may have rust and/or sludge built up inside the tank. Also, water in the tank from humidity and temperature fluctuations in the Little Rock area is very possible.
