Stalling under load

I have a 2003 F250 SCSB Fx4 7.3 stock except for a cheap intake. The truck drives fine if you keep it under 70 or 2200 rpms. When you go WOT or cruise at 75-80 it will stall. The injectors will start clicking loudly and it will lose all power. If you coast for a bit the power comes back and it will run fine in a few seconds just won't do 80 or pull to top speed it will stall every time. It seems like it is running out of fuel to the injectors. It has a new fuel pump, filter, and a new cps. It does have a minor high pressure oil leak but I don't know if that is the problem.

What's your fuel pressure?

Nonconformist. Functionality over bling.

My three rules for 7.3l troubleshooting: 1) Replace CPS and keep a spare. 2) Replace FPR and know your fuel pressure. 3) Hook it to a scanner and check for codes.

I do not have a fuel pressure gauge on it, but I suspected that would be the first step in diagnosing a fuel problem. What is the best place to tap into.
