Idk whats wrong need help

[NewClipse96]

Idk whats wrong withmy car but when im riding for a little awhile an it warms up when i go to get onto the gas it starts acting funny not wanting to go(hard to explain) but im thinking it might be the throttle positioning sensor but im not sure any ideas?!

Cat convertor maybe getting clogged? If that's the case it will get gradually worse until car is nearly undrivable.
