2006 Dodge Dakota Intermittently won't start especially in certain weather. Help!

What is your question?

I have a 2006 Dodge Dakota 3.7L V6. For a few years now, it will randomly crank over, but not start. It does this in the Spring and Fall when it's the "in between" temps. It will start and run fine first thing in the morning and then later in the day after driving it for awhile, you will go into a store for a quick trip, come back out, and it will crank over, but won't start. After the truck sits for 5 minutes or so after trying to start it, it will start right up. I have already changed the camshaft and crankshaft position sensors. There are no code readings on it. What else could be the issue?

What makes this problem better or worse?

Better in summer and winter. Bad in Spring and Fall.

How long has your 2006 Dodge Dakota had this problem?
