Truck starts great after sitting for 23 days.
When driving it around town the idle was jumping up and down and just now driving about 30mph it keeps wanting to accelerate in speed like its running out of fuel.
At idle its running just fine. What do you guys think i should start looking at as to what the issue is?
-Fuel filter is new maybe 700 miles on it.
-Fuel pressure from lift pump is 3-5psi on my gauge.
-Both tanks 3/4 full with month old diesel.
-I dont think its air in the lines due to it starting right up after sitting for 23 days with no issues.

I'd run some fuel cleaner a month old diesel could have rust or other stuff in there and could just check all your lines just to be sure there is no pin holes for air. Just a novice answer from me

Might very well be a sticky metering valve in the IP. I would try the filter full of ATF soak trick. Wouldn't hurt to try a fuel system cleaner like @Jason1377 said but an ATF soak may yield better results.

If you want to try fuel system cleaner find some hotshot extreme and dose it a little heavy. Run it around to get it mixed through and let it sit overnight with it in the fuel system.

Hotshot extreme is the best cleaner out there, amazing stuff.

Sounds like an IP issue or air intrusion. You can bring the truck by the shop and I can throw a good ip on to see if the issue follows.

If im driving to San Antonio to swap ip's im leaving with a new one on the the truck lol. Obviously paid for.
When i first bought this truck i drove from granbury tx to san antonio every 15 days lmao it had bad heat soak issues and would only start if i poured cold water on the ip but it worked every time until i got a new one installed.

"Distributor?"
They are my preference for additives, gas and diesel. I always buy straight from the website.
