Fuel starvation

I have a 98 GMC K-2500 pickup with a 5.7 liter 350. It gives me a hard time starting anytime the gas tank is below 1/2. Over half it is ok. It is also sluggish when I step on the gas to get it to downshift and take off (full tank or not). Just boggs down. I changed the fuel filter a few weeks ago, (might have made some difference, but no more). When I go to fill it up with gas, it always gives me a hard time starting when leaving the station. Is the fuel pump on its way out? Is this how they act when they are dying? Or could it be the fuel pressure regulator? Thanks for any help.

Have fuel pressure checked. From what you describe it could easily be a fuel pump.

Check your evaporative fuel cannister for signs of gas saturation which could contribute to excessive fuel intake as it purges. 1/2 tank means more fuel vapor, which can end up as gas in the cannister. This is a low probability cause if you have other symtoms as it sounds like you may have.
