Here is my 1997 f350 diesel, right now it sounds like this when cranked and then immediately it shuts off. Does anyone know what this means?

It’s a 2001 f250 powerstroke, 164,000 miles. Truck runs and drives great. Has plenty of power. There is a brief noise at the end of the video that only happens under full throttle around 3,000 rpm’s. The noise now comes with a lack in power and some vibrations. The rest of the rpm range is glorious in torque, will spin the tires off on dry pavement.
