It sounds to me like your idle relief valve is malfunctioning. This little device pictured below does a lot of good things but is a pain when not functioning.
• Regulates the amount of air entering the engine during idle.
• When not replaced, vehicle could experience high or low idle, engine dies at idle and/or severe high idle possibly causing internal engine damage and safety issues.
• Designed to meet or exceed OE specifications in form, fit and function.
• Global coverage for import and/or domestic applications.

I think that this is fuel pressure related, it could be any number of issues.
