When cold, the car starts and drives fine. After it warms up (5-10 minutes), it starts misfiring, almost like it's running out of gas. I try to give it gas and it bogs. The RPM's slowly drop while I give it a small amount of gas just to keep it moving, but it eventually dies. Then it won't start for about 35-40 minutes (cool down). Then it will start and drive just fine for another few minutes and start the same crap all over again.

Everything on the car is stock except what is in the sig. Never had any problems before now.

I pulled codes, but all it gave me was "misfire detected". Big help there.

I tried logging some data using OBD2, but I don't see anything apparent as of yet.

Any ideas?

Fuel pump, MAF, IAC?
