Sounds like the rotating assembly is looking to exit the block. Don't run it anymore. Have a mechanic diagnose it. If you continue to run the engine it could make the difference of having a rebuild-able engine or scrap iron.
It is reducing engine power because a sensor dictated a serious problem and to keep the engine from damaging itself it'll go to engine power reduced stage and it vibrates because its at a rough idle

That is normal operation.
get that car in the shop asap!!! the banging noise and the pressure drops mean that you have a serious problem inside the engine.get it fix right now or it's over for the engine
your engine might be overheated, causing the vibrations
Depends...by "diesel tractor" do you mean "farm tractor" or "semi tractor"? You're SUPPOSED only to put off road diesel in a farm tractor. That's why they make it. If you have put it in a semi tractor, get hold of your dispatch/brief/lawyer right away for advice on what to do. If you have a pre-2007 engine your trouble is almost exclusively legal. If your engine is 2007 or 2010 compliant, you're probably going to screw up your EGR and diesel particulate filter, which will break your engine.
The Ford 8N tractor was produced 1947-1952.
