2004 Titan Acceleration Problem - help

Looking for some help solving an acceleration problem on a 2004 Nissan Titan. Vehicle has recently had a full service and all fluid levels are good. Vehicle was taken into the dealer and full diagnostics ran with no faults found by dealer. Failure "typically" occurs when it is hot outside. The engine "cuts" out when the engine is loaded and will not accelerate. There are three videos on this problem. Any input is appreciated. Air filter is good, vehicle runs great when it is cold out, fuel being ran is Supreme Chevron with Techron. Do not suspect a fuel pump because it never does it when it is cold out. When engine cuts out, it sounds like one or two of the cylinders are being shut down by not getting spark. Transmission is not slipping and auto transmission fluid looks and smells good. I suspect an electronic problem, maybe a wire or sensor that is getting shorted then causing the computer to limit the engine. Sometimes the fault can be cleared by turning the truck off then back on, but sometimes not. Truck has never faulted when it has been cold.
Here are links to You Tube videos of the problem.
