Please run down this guide and report back.

Good afternoon,

First off, try and think of things that may have happened recently.
Did you get fuel from a different place than usual?
Did you notice anything just prior to the loss of power?
Have you scanned the vehicle to find out if there are any DTC codes?

Lets start with the basics here. Actually I had the same problem twice with my 7.3 diesel, one not too long ago and it turned out to be a clogged fuel filter. The other time it was a batch of bad fuel I got from a "questionable" gas station. The fuel was contaminated.

First thing I would do is change the fuel filter. Then see if the problem still exists.
Regards
Jon

Start with a compression test, you will need a special compression tested, as diesel compressions are extreme compared to petrol engines, and there will be an adaptor to screw into the glow port, if you do this your self, you will have to crack all the injector lines so the engine will not try and fire, if in doubt get a mechanic to do this test.

Injector could be sticking try loosening the fuel line to the injector on by one
