That sounds like the symptoms of a ghost throttle condition. could have a cracked injector.

It sounds like a PMD. My truck was going down the road and it began to accelerate then idle and kept this up. A mechanic in town told me it was my fuel pump, but after reading spent 320 instead of 1600 and the PMD is easy to relocate and install. Truck runs fine now.
