Acceleration issues with no check engine light

Hey, folks!

I have 2014 Toyota Tundra 5.7 that is experiencing acceleration issues.
2014 Toyota Tundra 5.7 V8 Acceleration Issues. I’ll be driving my truck, doesn’t happen all the time just here and there, but I will have my foot on the gas and then the truck just acts like I’m no longer putting my foot on the gas and drops in RPMs and won’t accelerate until I take my foot off the gas and re apply pressure to the gas and then it will accelerate again but repeat the process. It does not have a check engine light on. It doesn’t sputter when that happens. It’s almost like its not registering I have my foot still on the gas. Just looking for some guidance before I take it to a dealership and spend money. Please give me any insight on what it might be, thank you!
