do you have a voltage meter? i would be checking the voltage at the battery with the truck running. if you take the battery terminal off the battery and the truck dies then the alternator is not putting out power. if your truck is similar to the bit newer trucks you will have a light green and red wire going to the field terminal on the alternator. if so you should check the red wire for power with the key in the run position. it should be close to the same as the voltage you see at the battery.
