Here's where I'd start, there are two small wires under the steering column cover that go to the OverDrive button at the end of the Shift Selector. It it not uncommon for them to chafe through there and draw-down the sensor line to the TPS (Throttle Position Sensor) at the top of the Accelerator Pedal.

Look at this link -> https://b7445ba3-a-62cb3a1a-s-sites....attredirects=0

You may not be blowing the fuse yet, just confusing the PCM with the partial short.

This may not be it, but it's a Free Fix for a common problem you may already have anyway.

Next your TPS itself may be failing. Check the plug at connecting to it, next you might consider having it checked with a scanner for proper functioning or just replace it...

My 2002 F250 7.3 was doing EXACT same thing. It was the throttle position sensor. Part is very expensive new from Ford ($820 ) because mine is 1 assembly with throttle pedal. You may want to search for used. A Ford dealer (maybe others) can hook their scanner up and watch signal from the TPS to confirm.

You actually don't have to buy the whole thing. People have said this worked well as a replacement.
