Let me know if you need any direction with checking things. Also, if it is the brakes, they would be getting really hot and you would smell them. Also, let me know if the check engine light has come on. Finally, just for the heck of it, check the catalytic converter to see if it is plugged. That would cause a severe power loss. Many times they will glow red hot if plugged. However, that still doesn't explaine why the rpm's would increase but the truck doesn't speed up. Based on that, it sounds like the trans is slipping.
Let me know what you find or if you have other questions.
