Weird issue...what the heck...I need help

[roll_the_dice]

OK, so truck runs great...90% of the time except when I make a left turn. Weird I know. It will cut off completely when making a left turn. When I make right hand turns it is fine. I know it has to be a wiring issues (I think) where a wire is hitting something and shorting out the fuel pump or something else to make it cut off. Any ideas on the easiest way to track it down? If I sit in my driveway and turn the wheel left it does not cut off only when it is rolling...if that helps. Not fun driving and turning across traffic to cut off...any help or ideas are welcome.
