This truck is my daily driver. No modifications, completely stock.

The issue first happened a few months ago. I was at a red light when my speedometer and tachometer flicked off. I turned off the truck to hopefully reset something then the truck wouldn't start back up. Turned the key off, waited a few moments then the truck turned back on and ran with no issues. It didn't happen again until the other day I was driving, and the speedometer and tachometer flicked off, I just kept driving, parked and when I got back in it started up no problem. Today I was driving and didn't notice the speedometer was not working but when I got back in and tried to start the truck it wouldn't start. No clicking, no cranking. Getting plenty of power from the battery but no starting. Could this maybe be the speedometer sensor causing the issue?

Can I ask how you know the battery is good? it sounds like it might be shorting out internally. I would start with a CAN scan which runs through the computer systems in case you have a BCM or PCM going out. You can get a CAN scanner (Controller Area Network) which will work on most cars from Amazon.

Here is a video to show you how:
