Hi I'm Wayne, I will help you with this,
We had a truck in our fleet that did the same thing, kept i shop all night, pluged in outside, would start very hard, and miss for a several minutes and then take off, and run fine all day till next morning, at the dealer many times under Warranty, no resolve,
we replaced the HPOP, that cured the problem, so that is what I suggest to you.............
