Gets warm and dies...stumped
Gets warm and dies...stumped So the car is being tempermental for whatever reason 
Car has a LE 226/234 cam on a 109lsa, all the supporting valvetrain on stock heads/intake/tb, deleted all emissions extras, ewp lpp longtubes blah blah blah. Anyway the car will start up fine, idles fine and drive great until it gets warmed up...than it dies unless you give it gas but will start up and still idle fine. It had previously thrown an o2 code but that was awhile ago from an exhaust leak which has been fixed and o2s have been replaced, this issue begain a month or so ago so i just dont drive the car. Car has a mail order madz28 tune and its running rich. Have an appt set for a dyno tune with SRE but wanna make sure the car is ready to go so any ideas or help is appreciated.

Preciate the advice
Autozone can test the ICM. Have them do it repeatedly to see if it passes after it warms up. The coil can break down under heat as well.
What gets me, is that the only other device that acts like a bad o2 is a faulty temp sensor (In the pump). Have you checked that out?
