Loss of Power.....

[1badv6]

just got every thing tuned by the book and finally got to take the car for a spin, well it starts up fine but after a few mnts driving around it starts to loose power ???? but still runs.... the engine is just been rebuilt and I'm not really pushing on it at all but you can feel the difference ... what other info could I give to better pin point problem ??

is it just not building up any boost or is it trying to die on you?

boost is there, and idle is ok, i think it may be that its getting hot,...
