Answer
Hi Gina -

First of all I will need to know if the check engine light is on -

If so, then what is the OBD code displayed? To get it, you will need a special reader. I think Autozone does it for free.

If there is no check engine light displayed, it could be either the fuel pump, or distributor ignition module.

If the engine only acts up when warmed up, it is probably the ignition module.

Otherwise check or replace the fuel pump and filter.

Hope this helps -
