Unhappy Location of Fuel Pump Relay

My 99 F250SD is giving me a P 0232 code which is telling me my fuel relay is possibly bad. Does any body know where the fuel relay is located. I have searched high and low and have had no luck. Truck runs fine idling in the shop but you get out on the road and call for HP, it just wants to die, misfire and sounds really bad. Everything is stock except I was running a superchips safe tow program in it. I have now take it back to the stock set up and still am getting the P0232 code. I have checked my air intake and the fuel filter was replaced only 12K miles ago. Any help would be appreciated.

Check under the hood there is a box with several relays, I'll have to go see which side cause I can't remember but I think it's on the left.

I have 90k miles. This problem just happend suddenly. I has never acted like this before. I wasn't pulling a trailer or hauling a load. I also haven't recently filled the tank so I don't think it is bad fuel. My ford tech manual shows the relay in the center of the instrument panel but it is really vague.

The fuel pump relays on these trucks are NOT serviceable. They are integral to the Central Junction Box. This means you would have to buy the entire fuse junction panel assembly, if the fuel pump relay were an issue.
