So, I was driving to work the other day and my engine just quit on me (also power steering quit). I pulled over. Put the truck in park. Shut it off. Let it sit. Started the truck back up and off I go. This has happened twice (I haven't had the time to get to a shop yet). Also I lose cruise control and it won't be operational when I restart the truck. I believe it to be an electrical problem but I'm not sure where to start. Any ideas? Thanks.
