battery issue?
6.0 PSD
when its cold (less than 45) the truck starts rough as **** but about 200 yards down the road I notice that all of the sudden my headlights get noticeably brighter and the truck smooths right out. Now if I let it sit for another 5 hours or whatever and then start it again, it starts just fine no issue. It's only when it sits 12+ hours that it does this.

I would take a look at the condition of the battery connections and the batteries.
These diesels take a lot of amps to run the glow plugs and start.

So, figure 150-170 amps and the stock alternator by itself can only muster around 80-90 amps at idle, the batteries have to pick up the slack.
Keep in mind during that time with the GP cycling and the normal running draw, you add in headlights and a heater on full blast you're killing the system even more.
Also, keep in mind the FICM is highly dependent on the voltage it recieves and is easily killed. And once the FICM starts dying it takes out injectors with it.

This wasn't mean to scare anyone, just take it easy the first couple minutes with the 6.0 and a stock alternator.
I retrofitted a 3G for more idle amps, the second video is a stock 6G

Glow plugs are like a dead short for 30 seconds +/- before the starter pulls even more power from the batteries.
It would be interesting to see what that clamp on amp meter sees from the batteries during start up.
It's no wonder that batteries have a limited life.
