You have the classic signs of fuel starvation, most likely due to clogging of some sort.
You have already identified dirty fuel as the most likely culprit. Problem now is to clean the fuel delivery system (lines, filters) as best you can before getting to real help (tank cleaning).
Yes, clogging can take place at the fuel pickup in the tank. It's sometimes very hard to get to the site of clogging, unless you can easily remove the fuel pickup from the tank, or you have a large inspection port on the tank and get physically get to the pickup.
Depending on how bad the clog is, you might be able to blow it out or, probably better, use a wire inserted inside the pickup tube to punch it out. Sometimes this isn't possible due to the 90-degree fitting atop the tank.
But, make no mistake, if you have clogging from dirty fuel it's very likely your tank is dirty also and will need cleaning. The fuel will need polishing as well. You'll need lots of filters and filter changes to boot.
