this just started today. i drove to the parents house to help with the cow(i HATE cows) and when i got there i turned the truck off for about 1/2 hour and then went to restart, but it cranks for a good 7-10 seconds befor starting. then i get home and shower and go to get some grub and it cranks for like 20 seconds, almost didn't start.
im gona check the lift pump, but can a PMD do this also?

Doesn't seem as likely as slow fuel.

Could also be the OPS going south.

Could also be the OPS going south. or the lift pump or the filters clogged or the fuse is blown...

Check out the cheapy stuff first. Diagnostic checklist good start.

How old are your injectors by chance?
