CAN NOTGO OVER 30mph and or 40mph TRUCK STALL'S LIKE OUT OF FUEL

What is your question?

When driving you can not over 30mph or 40mph the truck stall's. if you put the truck in (N) and turn off the eng and re-start the eng, the truck will go again. It act;s like it is running out of fuel,If you step on the gas it will bog down but will start back up..Can a fuel press problem cause this to happen. or fuel filter. or more things. Please if you can give loc. of the items or were I can find them. Thank you.
