Miss

[buck 01]

04 6.0 6speed with 70,000 when my truck gets to a 1/2 tank of fuel or less it will start to miss just on accelaration but it dosen,t do it all the time about 3 or 4 times in about 40 miles. Just under 1/2 tank of fuel. when its above no problems at all truck runs fine. NO CODES

You may need to drop yhe tank and inspect the pickup foot, there is a bypass valve in the foot that is prone to piping out when the foot becomes brittle. Does this happen in conjunction with going up an incline?

Well what i've explained happens more at or below below 1/4 tank, maybe you have a cracked pickup tube. Sucking air.
