Mind being a little more specific than "dogging out".
I mean, I assume that means it feels like it's losing power - but what's the sensation like? Sudden? Slow? Smooth loss? Shaky loss? This is all important information.
Sir.b hit it with the pinched lines, but that'd be my thought on why the change of fuel filter stopped the bike running.
Beyond that I'd say you've either got the wrong psi fuel pump (should be 2-3psi or there abouts), shit in your carbies, oooor a loss of pressure somewhere in the system. Check your fuel hoses, breather hoses and airbox breather.
