Could you explain more about the problem and what engine you have in it. Does the SES Service Engine Soon light come on or is on. If its a Hemi V8 i have one possibility to check right away. The Hemi V8 was designed with a drive by wire throttle system. meaning it uses an electric motor to open and close the throttle blade or butterfly valve. This is known to gum up (on any vehicle) which causes strain to the electric motor. In most cases this will cause a light to appear in the lower right side of the instrument panel. But not always, if this is malfunctioning it will cause the engine to stop running because it senses that the computer is no longer able to control the throttle. If you have the Hemi in your truck pull the intake inlet tube and check to make sure if this is gummed up/tarnished or has any kind of deposits on or around the blade, if so clean it with a throttle body cleaner NOT carb cleaner, this will strip the enamel off the inside of the intake. Problem in doing this is you CANNOT open the throttle blade manually. You will need a diagnostic tool to control the computer in opening it to get behind the blade. Try cleaning it best you can and run it to see what happens, otherwise take it in to have it done. This motor is VERY expensive so maintenance is key to keeping it working as intended. Hope this is helpful
