I have a 2005 Dodge Dakota st 3.7l v6 automatic 4x4 123000 miles

Last year I started having issues starting the truck when hot. I was finally able to get the lock cylinder and ignition switch replaced recently. I also replaced all associated relays and fuses with this. When it is winter time i have no issues at all. But when it starts to warm up any like recently 70 degrees. I go to start the truck it turns over  but will not start. After the 3rd time it starts and runs just fine no issues. There are no codes on the reader before or after this happens. But it only does it when it is warm outside and truck has been driven but not all the time. Winter time not an issue at all. I have no idea what it could be? I had the plugs replaced in 2010 with iridium plugs and they have  only roughly 50000 miles on them. Any idea's or help please would be greatly appreciated. Thanks everyone
