Thanks for the suggestions Hot cummings

check and make sure the fuel filter is on there good and the bleeder screw is alright.

Here is a link to fuel system diagnosis.

sounds like a good possibility of injectors or cp3 ....

wierd! i dont think it could be the bleeder screw cause if it was then when it sat over night it would loose prime, i also dont see how it could be the injectors, could be the FPR or CP3 tho,

Sure it's not just a bad seal at the fuel filter somewhere causing it to lose prime?

if it loses prime when its warm its still gonna lose prime when its cold!!!!:tu:

unplug you fpr and see if that makes a difference, or have some one w/ a tech 2 go in and read what your fpr and cp3 are doin,

i have almost same problem but my truck loose prime when it is really hot weather (80 F +). or maybe summer blend diesel. i have no problem when its winter. mostly i have to prime it when the diesel tank is on at least 3/4 tank or less....this first happen when stealership changed my fuel filter and i have replaced filter many times now and still happen. the dealer checked everything fuel pressure, codes, etc....and they are functioning normal. please help and thanks in advance...... i am considering putting on airdog fp100 to maintain the pressure on my fuel line....:c:

same problem
 

Did you ever figure out this problem? I have the same problem. My trucks at the shop now:humm:

Had same problem with mine 100+ degrees would run about two minutes then act like it lost prime. Reprime get another two minutes. Put a bag of ice on fuel controller made it 300 miles home. Crazy!
