not getting any fuel?

my 87 b2000 is hving problems like it has had sense i got the truck!

ok if anyone can help me.

i cleaned out the tank,lines, new fuel filter,new fuel pump and it will idle fine but when you run it for a few seconds at a high rpm about 20 or so seconds it will start acting like it isnt getting gas. then let out of it and it iwll run fine. it seems like it fills up the carb bowl and isnt keeping it filled. weve vlew the carb out and everyything but take it apart and clean it out. what could it be??
