Throttle cutting out/Delayed from a stop

[97ls340]

So yesterday I noticed than sometimes when accelerating from a complete stop, my truck won't go. I can depress the gas all the way, and nothing happens. The RPMs don't, the truck doesn't move, etc. Usually letting off and pressing down a few times solves it. Like I said, it only happens sometimes. I'm thinking MAFS or TPS, but I wanted some other opinions.

You must have an 01 or 02 right?

Completely slipped my mind, yes it's an 01 sorry haha.

I agree it's a throttle body/ TPS issue. Problem is on those years they are sold as one piece so you can't just replace the TPS. It's expensive so I'd try a used throttle body first if it keeps happening.

not the right one. 01-02 have a 4 prong TPS, which is sold as a unit with the TB.
