What is the cause for my GT to die upon start up after it sits a day or so?

I own a 2000 GT and now after it sits for longer than a day it doesn't want to idle properly upon start up. If i keep my foot on the gas pedal it will keep running and finally idle just fine. No issues after that. One time last week at a stop light it did want to die but that has been the only time it has done that.

It sounds like a spark issue, change out the spark plugs and see if the problem continues.
When's the last time you changed your air filter. It could be that.
Thank you all for all your responses. I do need to change the spark plugs and will do that. I have been suspicious of the fuel pump as well and I will do the plugs and air filter first. I change the air filter every 2nd oil change and it is due. Thank you again and I will try them.
those mustangs a famous for leaking past the air cleaner that round thing after the air filter .its a black foam gasket that falls apart and wont seal causing the map sensor to read incorrect message from pcm
