Yes I will be googling and looking for it but figure I'd ask for some help.

History.

Wifes 01 5.3 L Tahoe, 92k on the clock developed a sticky fuel gauge float a while back. Did not feel like dropping the tank so told her to top it off and use the trip meter to guesstimate when she hits a half tank then top off again.

Been working just fine.

Today she calls, picking kids up from school. Truck won't run. Starts but runs rough and dies. Assume she is out of gas but she insists no. Neighbor runs up with a gas can and dumps in a couple of gallons but still no go.

Tell her to leave it and I'm on the way home.

Go to truck, starts but runs rough, peddle it and can get it to idle better but it's definitely starving.

Open airbox to check filter, it's clean so leave airbox open. Try to start again but now won't even run rough. (Just hit me, too lean due to open airbox)

Check fuse box, injector fuses all ok, swap fuel filter, ignition etc... relays with same relays from known working non essential components like A/C and horn. No start.

Assume at this point fuel pump is shot. Close everything up, come home and call roadside to pick the thing up. Look for deal on fuel pump assembly, damn these things are expensive. $250.

Roadside shows up, go to meet them and the thing starts, runs rough, need to peddle it to keep it running. Put on flatbed and they bring it home for me.

Last load of gas was last week, wife says it was running funny last week but I drove it this weekend and noticed nothing. Possible bad load of gas but doubt it.

Pretty sure it's a blockage somewhere so looking to check the obvious accesible points of failure before dropping the tank which is about half full.

Thoughts?
