All of the sudden it started shuddering and cutting out?

Hi I have a 03 Tahoe lt 5.3flex fuel about four days ago a'll the sudden it started spuddering and cutting out to the point I had no acceleration like it was starving for fuel so I read that this happen to someone else in a Gm forum and the service tech said to try replacing the fuel filter so I did it that day and had absolutely no issues until tonight when my 3 year old were on the way back from monster jam it did the exact same thing again so I made it to a parking lot turned off the ignition and let it sit for about three minute then I crunk it up and drove home what could be causing this issue I've thought I it was the fuel pump first but after I replaced the fuel filter it did great. The only thing I've done different today is unhook the battery because I put a k&n filter In a week and a half ago I read on the box your suppose to reset the vehicle after installing it. But keep I'm mind I had this problem prior to unhooking the battery so I'm sure that's not the what's causing the issue. Also I read that the crank position sensor could cause similar outside in this truck what's your thoughts? Thanks
