Thanks Guys; I was leaning towards a sensor too.
I've got a buddy that a retired electronics engineer
and we are gonna check those first.
I don't think it's turning up the fuel needed for cold
weather starts. I only run premium fuel and I know thats good.
Fuel filters are new so this should not be the problem.
I do drive the truck almost every day and have had no problems

Thanks to everyone for your time and input,
I think Ted & HWORRELL hit the nail on the head I'll let you guys know
what we find out. Thanks to all Kurt
