What causes a Chevy C / K 1500 to bog down?

My truck bogs down (and tries to die) when I give it gas to accelerate off of a stop. There is often a backfire or two when this happens. Pumping the gas does not help.

Up around 65-70 it is very bad. RPMs at 65 mph is around 1700.

If the diaphragm has ruptured it will literally be like putting a hose with fuel into the intake and running it full.
