96 Eclipse spyder 2.4L, Car dies once it warms up.

I have a 1996 2.4L eclipse spyder GS. I bought it and had to clean put the fuel tank and replace the fuel pump and filter. I have replaced the plugs as well. The car was running fine. One day I cranked the car and it idled until it warmed up and then stalled. Now if I crank it it cranks fine but dies once warm (temp gauge gets about 1/8 of the way up). I have replaced the IAC (with a used but certified to be good IAC) on the car thinking it is a idle problem but that did not fix it.I check the voltage input to the IAC on pins 2 and 5 and there is 5v coming in. I am wondering if it is the PCM. I am kind of at a loss and the check engine light code reads P0505 idle air control general.
