dodge ram pickup 1500 v8 engine bogs down when driving

Engine bogs down and wont go anywhere when in drive almost like its not getting its fuel. When I pull over and put it in neutral or park and rev motor a bit it sounds great,no miss or bog. Doesn't  try to stall or anything like that. In a few minutes bog goes away and truck runs great until I shut it down for a while. It starts great then when I try to take off in drive bog starts and then goes away in few minutes again. Truck not holding any codes. Is this a plug and wire problem or a fuel problem,hopefully a fuel filter or a bad wire and not a fuel pump or timing belt. Would appreciate any advice you can offer..Thank You.     Drew Scott.
