Ever since its been warm out, my 09 ss will hit a certain temp and just die. It taked a few tries to get it running again when it does this. I've replaced the MAP Sensor and cleaned the throttle body since when it was last scanned the IAC code was popping up. Still dies in the hot weather. Last time I had it scanned the codes for the Vapor Canister anf the Canister Purge Valve showed up. Is a clogged canister and a bad purge valve what could the cause here. Any insight is definitely appreciated!

 

I would start with replacing the Evap Purge Selenoid on the intake manifold. Super easy 5 minute change. Very common failure.

You could pull it off and test it by blowing through it but that doesn't always show if it's bad. Could be stuck closed.
