2005 txrd f150. Have had great performance with this engine. 650 hours and is acting like it is loosing fuel pressure. Starts well, idles smoothly at start, runs good for a minute then progressivly slows down to a crawl. Changed the plugs (uniform color tan electrodes), fuel spin on filter, oil and filter, front fuel filter filter checked(Cylinder full of fuel and some particulates)cleaned and replaced. What am I missing? Apparent cylinder drop.

Need to have fuel vacumn test run to test for restrictions in fuel supply and fuel pressure test run to see if loosing pressure to injectors. -
sounds like a problem with your head or lower unit..Good luck!Comment

thanks for all of the responses. one of the injectors was clogged, the others were cleaned and it ran great. one week later the crank broke outside the block at the flywheel. $5500 later it runs great but has a oil leak where the block bolts together. this has been an ordeal and it looks like i will hane to repair this one. is it hard or too technical for me and my torque wrench to handle?Comment
