Dead spot in pedal

Hey guys I'm experiencing a "dead" spot in my acceleration pedal. But it only Happens when the truck is in o/d with the converter locked. The first 1/4 of pedal feels normal. After that it dies. Could it be my pedal or what? Oh and I doesnt do it all the time just every now and then. Thanks for any help guys.

Is this dead spot like it just doesn't accelerate more or the truck acts like you let off?

There is a sensor on the pedal that when it goes bad it'll cause the PCM to see 0% throttle pedal.

Mine scared me, it would let me take off, then the engine would drop to idle. Took that happening 1 time while crossing an intersection to get it fixed. Apparently some people have luck cleaning it. I just replaced it with a junkyard part.

Its like it works full pedal while the tc isn't locked but once it locks in o/d its like the truck doesn't accelerate it doesn't die like idle but still has like 25% power. I have a spare pedal at home I'm gonna have to try before I get stuck in an intersection.
