Hello, I need some help!!!
I have a 2013 F-150 Platinum with 160,000 miles. Today I started the truck in the morning to go to working like any other day. Whenever i got off work this evening i went to start my truck and didn't want to start. It crank strong but the engine didn't start. I locked the doors 2 maybe 3 times with my smart key and tried to start it again and ran fine. The truck ran perfect like always till i got home. I waited 2 0r 3 hours and went outside to try to start it and it did start fine, I stopped it locked the doors and unlocked them back, try to start the truck and was cranking but wont start. Again I locked/unlock the doors 2 or 3 times and i was able start the truck fine.

Can somebody please tell me what's going on here?

Thank You.
