no gas pedal response

04 fx4 no mods. Throttle doesn't respond sometimes. Driving along and the gas pedal does nothing, the truck continues to run and idle. Turn truck off and restart and truck drives fine. I found an old repair to wires at exhaust pressure sensor harness. I disconnected the harness and drove around the block. Should the truck run with the harness disconnected? Does this mean the harness repair is fine? What else should I be looking for? Also, the truck runs rough when cold. Checked ficm voltage and I have 48v all the way through start up. Could my 2 problems be related to a bad repair at the sensor harness?
