That really sounds like a carby thats trying to run too richly,
chances are that its adjusted ok if it was running well before, but
you may want to check the float to see if it has developed a pinhole
and is filling with fuel(makes it sink) and maybe the float valve
sealing surfaces for dirt/damage or just coming loose.
Usually in a fuel starving situation it will die off or cut out
periodically and have a fall on its face flat out power loss at
higher rpm's, regardless of throttle position.
