Well, I guess it starts but won't stay running. My first thought was fuel or fuel pump but it acts like the thing was just turned off. If it sits a few, it will start right up but then shuts right back down. Ran fine comming home from work last evening. Any thoughts?

 

Ignition switch? You might scan for codes to see what comes up.

You may also have a bad ignition key and the truck isn't seeing the security chip. Do you have another key you can try?

 

It starts fine with my wifes key and later started fine with mine. I'm hearing that the key might be the key from several places. Thanks
