Fuel problem in 89 chevy suburban

The other day i was at some podunk gas station fueling up, must i also note it rained for 2 days in a row, and then that day dropped to about 10 degrees, and its still colder than hell.... Now comes the problem, about

1/4 mile away from the gas station, the thing started bogging down, not running properly. Its been doing that for about 4 days, it kind of idle surges if you will. It'll run normal, then bog down and shake, then normal and repeat, while driving it runs bogged down all the time, unless i stomp on the gas, in which case it will stay bogged down for like 5 seconds, before finally going into full throttle, usually resulting in spinning the tires loose and damn near crashing into a tree. My first thought was water in the gas, seeing it came from a questionable gas station, i had about 1/4 tank of the bad gas, so i added a couple bottles of water remover and filled it to 1/2 with premium. after 2 days like that the problem was still there, so i changed out the plug wires, plugs, distributor cap, and rotor. and im still having the problem. It was running perfect up untill that gas station. Further note, tried to replace the fuel filter, however all the nuts are rusted and locked, tried penetrating oil, not gonna work, so if the fuel filter is the problem (which is may be) if anyone has any advice on how to cut the lines and bypass the old one that would also be appreciated. I also was wondering about the possibility of a fuel pump failure causing this? i dont know a ton about the fuel pump setup, but im also thinking that could be a possibility. Thanks for your time all, and im sure working on this thing in snow 2 feet deep and temps in the negative digits will be the time of my life....

Try some Fuel INJECTION Cleaner into the GAS tank!!! And Try to keep it Running For about 20 to 30 miles
