I'm loading some parts into the back of my idleing truck tonight when it starts to stutter and run rough, after about a minute it died. Now it wont even crank over. 13v on the guage, lights come on in the key on position but you dont here the fuel pump, or starter sol. If you twist the key to the start position the lights go out completely and nothing happens, no crank, no sound at all..nothing.

Any thoughts...
