When im driving down the street in any gear if im driving normal about 15 to 20% throttle it acts like the motor dies but but it dosnt die it just cuts out really bad and keeps goin and it will just randomly do it the whole time im driving but if im giving it about 50% or more throttle it dosnt do it. I have everyday driven this truck for the past 2 years keeping up on routine maintnance and it just started doing this like 2 weeks ago and i just dont know the first place to start and im expecting a child and a rough winter so if anyone has any idea i would greatly appreciate the help thanks!!!

When your not sure where to start, it's often good to check for any codes the computer may have stored.
My first thought would be a vacuum leak.
After posting, I was thinking a thorough visual inspection & connections check, but..........it was too late! Then there's the condition of the ignition system componants, ect,ect,ect...
