Almost dies at stoplights?? need help please
I've noticed that when I stop at a light my battery starts loseing power and everything starts to dim and my engine rpms go down, I can hear my fuel pump start to die down, everything starts to go almost like its loseing power but its doesnt lose ehough to kill it. But as soon as i let off the break pedal its fine, but when i press the break it does it again. example.... I will be at a light pressing on my break pedal and my break lights are on, the battery seems to lose its power and everything starts to die, but when i let off the pedal just enough so that the truck stays stopped but the break lights arnt on anymore its fine..

Your Idle air control valve (IAC) could be the problem. It could be sticking a little, so the engine isn't idling high enough, and then the alternator isn't spinning fast enough to put out enough power. You could pull the IAC and spray it with throttle body cleaner and see if that fixes it.
