'04 QX56 cuts off and the security key light luminates on the dash, what's wrong

[slouchie]

My truck may shut off while @ idle, and sometimes im not able to start the car back for a few minutes.. the security key light is luminated and in the manual it just states, when this happens bring it into the dealer right away.. Do anyone have any idea what the problem is before I get robbed?

That sure doesn't sounds good! I would call the dealer ASAP and see if they have any ideas, very strange!
