2005 ford exploder starting issues

So I have been at basic and ait with the military since july. I came home for xmas and my explorer seems to have a hard time starting whenever its cold. It turns over really slow and then slowly seems to come to life. Then the trip computer goes into some weird test mode and acts funny. My explorer has been driven atleast 3-4 times per week since I've been gone with no issues up until now. Any ideas? its a 2005 v6 flex fuel 2wd xlt thanks for any info!!!

Make sure the battery cables are clean and tight. If they are, then you might be due for a new battery. Many chain parts stores will load test the battery at no charge.
