Check engine light when temperatures in mid 80’s or higher

[Shanewint1315]

Been having this issue for the past month. When it’s hot outside the truck gets a check engine light throttle will cut out like there is no power at all will come back after few seconds.If I have the cruise set I just get the check engine light but truck continues to run fine just can’t use the throttle pedal till the light goes off. Codes say TPS replaced that still having the same problem. Never have problems when it’s below 80 degrees outside. Engine is a 2012 cm 450 isx any help is appreciated.
