That same thing happened to me too, right in the middle of a turn....

"dont turn the truck on only on aux mode and try to hear the fuel pump cut on ( it should sound like a high pitched hum from behind you ) might have to have somebody turn the key so u can listen." this is how i knew when i had it fixed actually had to put my had on it and felt it turn on...

Well as it seems it was the battery, I've changed it and it fires everytime i start it now...I'll really know in a few days if it happens again.
