NEED HELP. Sudden lost of power, rough idle/loud knock

Need some ideals on what to dig into first. This is my first diesel. My 2000 F350 SD (189,000 miles) which ran find and strong until yesterday, I was coming down the interstate when it just lost power and the check engine light came on. It also lost boost. All gauges were fine. Pulled over and looked under the hood. Truck started a louder than normal knock. After looking it over I decided to try and limp it home. Truck has almost zero power. Would only run 30-40 mph and would have to downshift on hills and slow down to 15mph. EGTs were several hundred degrees higher than normal. Boost would only hit 2-5lbs. Truck will start but idles very ruff and knocks. Check engine light is still on. Any help will be appreciated! Thanks! BEN

Check the wiring harness under the valve covers! If on is disconnected, apply a 50cent fix.
That happened to me a while back!

What's a 50 cent fix?

02 F350 CC 7.3 PS, auto, 6x6, 4.10 gears LB. AFE stage 2 intake, 4" AFE SS exh, 6.0 atf cooler, DP tuner with five stages Eng Temp gauge, EGT guage and Trans temp gauge. J.Woods valve body ATS turbo housing. Cooling sys filter & waterless coolant. NON WORKING POS FASS fuel filter sys. Brightbox headlites. I don't care what they say "There's no replacement for displacement." Don't believe statements about anything being better than a 7.3
GOD BLESS AMERICA!!!!

You put a quarter or two underneath the plug going into the valve cover gasket. It takes the slop out and keeps it from bouncing or coming apart from vibrations

Is that inside the valve cover or on the outside? I was just in there so I can visualize it.

In regards to the 50 cent fix.

If you ever think something I post is ridiculous or uneducated, just remember that I probably learned it from here.

The video says that it won't work on the 02/03 7.3s I have the 02 and couldn't get anything to fit in there. So I guess I'm done and hope that never happens again. I do now have the injector harness I removed from the d.s. that was in useable shape. So I'll keep it and hopefully MANY years down the road I'll remember this if it happens again.
Thanks for the information.

I would check to UVCH or actually the harness that plugs into the outside of the valve cover like they said, and after clicking on the video, it hits right on the head. Let us know if this is the problem!
