1999 chevrolet diesel 6.5l. some symptoms of a bad injector pump

starts just fine. sometimes it wont start.

sometimes wont rev past 1700rpm with foot to the floor

when i rev the engine past 2k rpm it hang up and revs up and down by itself with lots of black smoke, then the truck dies... it will start up just fine after it dies.

you can see i rev it to about 2k rpm and take my foot off the pedal. the engine keep revving and rpms bounce around then it dies
