My 2004 f250 with 129,000 was on a road trip 300 mile from home running fine and when I try to leave a stop sign the pedal will go to the floor and it just keeps idleing. after a minute it start running rough and dies as if out of fuel and then dies and will not start. It has fuel and the pump is running. I am way out in the country near Kerville TX so I do a computer reset and it starts right up and seems to run fine. There are no codes on the bully dog programer before or after this. After 15 minutes it does it again, another reset and it last for 25 minutes before the next spell. This is Sunday afternoon and there is nothing open and have it towed to the nearest dealer, they jumped on it monday morning and it ran fine and has not repeated the problem again. It did this same problem four years ago and had to be towed and nothing was ever found that time either. I cannot trust it to make the 370 mile trip to the deer lease without a positive solution. Any ideas or is it time for a new ride?

 

Cannot say for sure but mine did almost exactly the same thing on July 4th. I have narrowed it down to a problem in the Vref circuit so am waiting on the delivery of all new pigtails for the main wiring harness and a new IPC sensor.

 

Sound like you may be loosing the Vref so to a short somewhere.
One guy spent a lot of time chasing one and turned out to be the
EBP sensor was shorting out. If you have something like the SGII
that will read live data watch the Vref and if it drops then you know
where to start looking in the system.

If it happens again unplug the ebp and try to duplicate the issue. Stuff like this is very hard to fix, you disconnecting batteries and trying to pull codes with a buly dog is not going to help you.
Bully dogs are crap when it comes to a code reader, theres lot of codes that dont pull and a few they create when done with a correct tool.
