Umm im not familiar with how the fuel works exactly, but the bogging sounds like it would come from no fuel, maybe, i guess it would have died if it ran OUT of fuel but i wonder if it would just lag like it did if the fuel pressure dropped signifacantly...

I think that maybe the fuel that you put in hasnt made it into the lines and up to the engine...

That would be my guess im pretty sure that if you turn your key to the on position the fuel pump will turn on and pressurize the lines, MAYBE you need to take off the fuel line at the filter (your filter could be clogged too, also causing this same problem) and bleed the air out of the fuel lines...or just crank the engine to bleed out the lines but who knows how long you would have to sit there cranking...

Hope i gave you some ideas...
