Having the same exact problem, with a 2000 Bravada. I think that maybe it was overfilled in the past and has messed up the vent system somehow, but not sure what part/s I need to repair it yet. Good luck.
The evaporative emission control system ( a pollution control device that recycles gasoline vapors) may have a problem not allowing your fuel tank to vent when you are filling it with gas. Try another brand of gas I had problems with one brand of gas being a little more temperamental to fill than others. Another possibility is that the fuel fill hose to the tank is restricted or damaged.
