Jordan's NBS Build Thread

I don't have a garage at my current house and it's like 10 below out right now. I'd rather pay to have it done by someone else.
 
Well, I had to run to the shop today to pick up a few things from the truck before work. I had a spare key so I tried starting the truck and it fired right up on the second try and ran for like 5 minutes without a problem. Mechanic said he also started it and it ran okay for 10 minutes or so. I'm so damn confused. I wonder if since it had been sitting without being driven a lot if there is some bad fuel in it or something.
 
Yeah, you're probably due soon too, huh. It felt like it was kind of down on power for even a stock 4.8, maybe this will fix it up.
 
My dads 01 sierra has 208k, running original spark plugs and fuel pump, only things he has ever replaced on it was the front rotors(uses a 1500 truck w/ 2500 plow) and rear leaf springs, and rust work....
