I left Bill a message. I don't know what to tell you other than get your battery tested and double check all your connections. It may be a sign of a low battery since right off the bat your battery is at its lowest. Once the engine has been running for a while the charge gets built up more and it is able to warm up a little bit.
I recognize your truck. I remember having some of your pictures show up in my photo albums during a forum hickup...about the time you joined.
