Make sure you have adequate fuel pressure and your fuel filter isn't clogged up.
Then I would check the TPS (Throttle Position Sensor).
Make sure the MAF sensor is clean.

How do I check the TPS!?
Yahoo search adjusting tps on a mustang and muscle mustangs and fast fords article will pop up, I just read it two days ago. It could be any of these problems, you will want to check the cheaper things first, mine was doing same thing and would eventually die. My order of finding problem was changing fuel filter( 10 bucks ish) then cleaning iac ( 3 bottle of throttle body/maf cleaner) then I changed fuel pump and it ran great. U will need a voltmeter to check tps, it's not a job that you are gonna want to Experiment and do
