Hi Gary this is lostrider, the concern your having is getting to be a fairly common concern, the voltage amplifier in the FICM (Fuel Injection Control Module) has gone bad, it takes the battery voltage and increases it to 48 volts to drive the injectors, the FICM will have to be replaced to repair the concern, the FICM is also a programable module and will require it to be programed to the truck, and that means it will have to go to the dealer for the repairs, If your truck has less than 100k miles on it the FICM is covered under the diesel engine warrenty with a $100 deducable, if not that module retails for about $800. hope this helps.
Description and Operation


Fuel Injection Control Module (FICM)

The FICM receives information from the PCM, including the volume of fuel desired, RPM, engine oil temperature, injection control pressure, and others. The FICM then uses those signals to calculate fuel injection and duration. After calculating injector fuel delivery time, the FICM sends 48 volts at a 20-amp pulse to the correct injector so that the correct amount of fuel is delivered to the cylinder at the correct time.
