Weak fuel pump and or clogged spider injectors (poppet valves. To check the fuel pressure hook a fuel gauge up to the port on the fuel line up by the intake. Then turn key to on position but don't start the engine. Pressure should read 58 to 64 psi. If less than that you have a weak pump which these trucks are famous for.
Updated spider with multi tec injectors to resolve this problem. This was actually a recall in cali because of the $hitty fuel there was causing all kinds of these poppet valve spiders to fail and clog up.
