I have had this problem for a long time, but it has never bothered me until lately.
During the winter, I have no issues, but the summer is a different story.
New battery was my first step, installed a Gel Red top.
Get in, drive, enjoy your ride but when you get to your destination turn off the truck and BOOM, your screwed. I usually wait about 15 minutes and when I turn the key the truck starts like nothing is wrong.
Usually, what I do is get mad, and rattle the battery, and that has made it start. Usually, just opening the hood and cussing has made it start, but that doesn't always work. Well, I just crawled under the truck and took the starter loose in hope I would find a loose connection on the starter. It was tight.
For some reason, I have heard a tick, and after it ticks the truck will start. The tick sounds to be coming from close to the battery bay, but I am not sure.
So, I wait until it cools off, and it will start right up and drive.
Any advice will be appreciated.
