I just bought this truck . When it gets up to operating temp the motor will just stall out unless I keep the rpm up to 800 or higher. I have replaced the throttle position sensor already and still no luck .

Welcome, better "Aloha".

Nice Blazer.

IAC maybe?
I guess that is a TBI fuel injected Blazer. Check all the vacuum hoses to the various sensors (MAP) and auxiliaries.
