97 Firebird stalls out when engine temp

[Dale K]

above 205? 97 Firebird runs great until temp gauge reads greater than 205 engine will miss a couple of times finally it will stall Cannot restart it Pull spug wire first coil pack No spark after cools starts v6? Ignition module checked GOOD but was checked when it was cold. No codes.
Ignition module checked GOOD but was checked when it was cold. No codes. New Coils/wires/plugs/ECM. Could BCM cause this problem... Security light is always on.... May have one than 1 problem... Someone said the ECM will shut down the ignition if the temp is too hot.. is that true.

You may indeed have multiple issues I would bet the ignition module is overheating and causing at least part of your problem but the security light is probably an ignition switch lock cylinder problem ..
you may have to take it in to have it properly diagnoised..
