truck starts and runs fine while its cold (has not been run) once started and driven so far (usually only on warm days no problems when cold weather) it starts to stall, right before stalling the check engine light comes on. I have run the engine codes and replace the issues that were listed but with no real progress because the problem is still there. I just recently replaced the ignition control module and still no progress, Please help!!

It could be the idling speed is too low. Try cleaning the throttle body and IAC. What trouble codes are you getting and is the code still present?

You might have a vacuum leak causing the lean running condition and stalling.
