Cutting Out?

This cutting out business is getting worse. Truck completely died on me today after a WOT run. I really wish my fuel pressure gauge was hooked up because maybe my Air Dog is messed up somehow. Do the seals where the DV's are seal in the pressure? Or are they just a dust/dirt seal, because a few of mine weren't in the best shape. The only other think I could think of is if maybe one of my injection line nuts are loose and under a higher pressure it leaks and pulls in air into the system.

Wouldn't it leak fuel since its under pressure if that were the case.
 
I see a tiny bit of fuel on the delivery valve holder o-ring, but I'm not sure if that's from when I installed them. I was thinking the same thing, but I'm kind of stumped.
