hesitation/stuttering only when hot - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'm having an issue with my 00 (classic bosy 5.7) hesitating or stumbling when at operatint temp, but only when its hot outside. I checked fuel lines, exhaust to see if it might be vapor locking but I don't see anything out of the ordinary. Fuel pump has been changed, as well as the fuel filter, wires are new, pulled and cleaned mass air sensor. Also the problem is much more noticeable when the truck is loaded or pulling a trailer

Any other ideas?
