97 f800 shuts down with acceleration
 

My boom truck idles great starts of good but with acceleration dies like its out of diesel. Anybody got any ideas? Because I cant find any info on the web. Please help & keep in mind that I recently inherited 3 diesels after my husbands murder & know ZERO about being a mechanic although I did get our 06 350 SDPS 6.0 diesel running again after replacing the IPR. I only know where fuel & cooler filters are. Is there a manual I can download?
