Hello. From my experience with this truck this is usually caused by a wiring issue on that side of the engine. If the ground loses connection then one side of the engine will begin to misfire and this will occur. I usually check the grounds and all of the connections first. If they are fine then the issue may actually be the computer.

Further testing with a voltage meter and a scan tool would be needed to make for sure. If you want to have this repaired, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose the loss of power firsthand for an accurate repair.
