Stopped to eat and car cranks but no start. So I left it the the next day came back turned the key to listen for the fuel pump it was working and then it just started up. Like nothing. Took it home about 25 miles. Parked later on went to store and after I went to go home again no start only crank. I don't know why.

This sounds like the crankshaft angle sensor or the fuel pump has gone out. when you turn the key to the on position without cranking the engine over can you hear the fuel pump run in the tank for 5 seconds? These guides should help us fix it:

Also, lets run the codes to see what come up.

Here is how you can change the crankshaft sensor out if you hear the fuel pump running still. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.
