So, I got this vehicle and one day the starter went out. I replaced starter and it was starting and running fine, until I ran an errand. I try to start up after driving and am getting a no crank no start again. Thought the new starter was defective so I went and got another starter. Same thing is happening after driving around getting no crank no start. When I let the car sit for about an hour and it cools off, I can get it started again. I got the heat shield on and everything, totally at a loss.

It sounds like it could be your alternator. Try starting the vehicle then while it's running disconnect the negative cable on the battery. If the vehicle stays on it's not the alternator but if it dies then you know what the problem is. Good luck and be careful

Yep, there is a starter relay I would replace. here is the location so you can swap it out and I have included the starter wiring diagrams so you can see how the system works. Check out the images (below). Please let us know if you need anything else to get the problem fixed.
