I start my truck up and after a few minutes the rpm starts dropping then my truck shuts off.

Will it re-start as soon as it shuts off?
Does it do this while setting still or while driving or both?
When it shuts of does it sputter and dies or does it shut off like you turned the key? When you first start it does it start easy or do you have to hold the throttle open some?
Is it repeatable, if it does it every time it is started?
Does it seem to be different if it is hot/cold outside?
You say rough idle, if you give it some throttle does it stay running or does it still shut off?
