Default Engine Problems 94 GMC K1500 6.5 turbo diesel

Hi all,

I have a 1994 GMC K1500 6.5ltr Turbo Diesel. What its doing is everytime i get up to 3000 rpm's it acts like its trying to vapor lock or sieze up/truck isnt blowing any smoke once its up and running idles fine and sounds good until i hit the 3k rpms. Checked all the fluids etc everything is topped off enough gas as well.
any suggestions or help would be greatly appreciated

Thanks,
Honda2k
