7.3 fuel problem

[Ed Fast]

Ok here is what I know. I am driving home from work turn to go up my street and my trucks puffs and chugs and dies. I roll down the hill in reverse and start it back up like 3 times make it home. My roomate get home I take his truck drop some 911 in and she runs fine for about 500 miles. Then I am out of town and the same thing happens. takes a bit more to get her going but she runs. i originally thought I was gelling but last time was too warm so i was thinking bad fuel. Now the fuel seems fine but she will run for about 20 minutes and die. Then if I wait a few hours I can go out start it up and go again. when I will no start it will run off wd-40 but I know it is not getting fuel. I see no check engine light come on. I am confused. when I turn the key over to cycle the glow plugs the check engine light comes on and then go off like normal. I am not sure where to start. Also smokes a little white when I turn it over. There is fuel in the bowl and I have change three fuel filters. Thanks for the help also sometimes my tach is not bouncing when I turn it over.

If your tach isn't moving it's CPS

can that be possible to run at times and then not others like that?

Mine ran bad right before it went out so yes, I guess it could run and then quit.
