Dead Pedal

Dead Pedal
Had 3 separate episodes dead pedal on my 04 bone stock 6.0. About a week ago I pulled out on the road and the truck went to idle and would not respond no matter how much throttle I gave. After about 10 seconds it woke up and took off. Had this happen 2 more times this afternoon.
No codes or dash lights
Ideas of what this might be? I have a 500 mile road trip this weekend and am worried about being stranded on the side of the road.

The throttle pedal has three track resistor that can be measured. If you have a scan gauge you can check it like this:

If you don't have a SG the values above should still be correct. Some have posted simply wiggling the wire harness under the dash will make it stop. This can be more common of a problem on a truck with adjustable pedals.
It it also possible for it to be a high pressure oil system leak or a bad ICP sensor or IPR. Short of wiggling the harness under the dash you're going to need something to check for codes and read live data.

Checked the pedals, dont see any wire chafing, the plug is in there tight. I wanted to pull the plug and reinstall but I cant seem to figure out how to remove it. I did notice there is what appears to be a sliding red lock on the right side but that still didnt get it out.
I am thinking it could be ICP based on other posts with a similar problem. The weird thing is that I have no codes so I am on the fence as to if I just replace the sensor or wait for the problem to happen again and or get a trouble code.

Try to reset with the scanner or disconnect batteries and turn headlights on for a few minutes. It prob set a code from starting with ICP disconnected. Alternatively, it should clear after a few drive cycles if it's plugged in correctly. Was the harness/connector oily? Can you monitor ICP/IPR values with the device you're pulling codes with?

ScanGauge II TPx success?
Has anyone had success with TP1 and TP2 setup mentioned below? I'm trying to diagnose an intermittent dead pedal issue and have double checked the programming.
I have the ScanGauge II connected to my '05 F250 but I get 0.00 on TP1 and nothing on TP2.
Any insight would be greatly appreciated.

I later had some throttle pedal issues and tried these scangauge codes myself. The first one worked well (AP%) but not much luck with the others. The voltage values were from the workshop manual if I remember correctly. I also Ohm'ed out a known good throttle pedal and have the resistance values for that somewhere if you want me to post them you could check it that way.
It may be just a fluke but I've had 2 trucks -and read of a couple more- with a dead pedal and one of them wouldn't crank (turn over with the key) that turned out to be a bad EBP sensor. Just unplugging it allowed the pedal to work. Worth a shot to check.
