2002 Chevrolet Express Van 5.7 1500 has little to no power going up hill it goes in to passing gear but it just revs up and drop power real fast?

Does it also do that when you press the pedal down more than say halfway on flat roads? If so, its the fuel filter clogged. It will run fine, but under load it will not allow enough fuel volume.....Its like having no secondaries on a carb.....once you go to far on the throttle it bogs because too much air not enough fuel.......
If that is not it, then have you had it checked for codes?

Replaced fuel filter. Still will not start on its own. And still no power when pressing on pedal about half way. But will run and idle fine I just have to build up speed to make it up even a small hill or go about 30mph. And spray starter fluid to start?????
