What's my truck doing?

I was backing the truck out today and it killed on me. When I got out I saw dieseldripping somewhat heavily on the ground near the rear passenger side of the engine. I haven't looked at it real carefully yet, but checking briefly up top I couldn't see anything, even in the valley. On the bottom, looks like it's running down the back of the block and hitting the flywheel which is slinging it to the passenger side. I'm gonna look at it closer later.

On the truck killing, it'll be just sitting there idling then have a "miss" or die. Ran Autoeninuity and the only code that came up was when I did the cylinder contribution test- P0269 (Injector Circuit Contribution/Balance Fault). No cps codes or anything out of the ordinary other than that. It had missed on me once or twice before over the past couple of months, but it's started doing it more frequently this week.

Oil and water levels are fine, no fuel smell or feel to them.

Any ideas?

Only other known thing wrong is a leaking up-pipe, which I'm addressing next weekend.

i would still check the CPS - when mine failed i never even got a code and it would try to die and sometimes actually die.
hope you get it fixed.
on the fuel definitely check those o-rings, this fuel has been eating them up on some of the trucks i've seen. maybe you have a leaky hose fitting on the reg kit? is it fed in the 1/8" port or the big one directly in the back?
does a bad UVC cause some of these symptoms? cutting out, code, etc?
are you feeding the fuel directly into the back of the heads? those fittings are a bit lower - maybe bad hose end or something? or the plug could be leaking...?
