    I forgot to mention I rebuilt the fuel pump. Its definitely a fuel problem, but Im confident its not the pump.The pump works fine at slower speeds. Also if the diaphram had a hole in it would burn an excessive amount of fuel and possibly foul the spark plug in the cylinder that creates the crankcase pressure that powers the fuel pump. Thanks for the input. I do have a diagnosis, Im looking to see if anyone comes up with the same diagnosis I did.
