Small block 350 chevy low idle when warm

[Kendell]

94 GMC 2500 with 350ci engine.

Idles normal when starting cold. After driving and getting it up to operating temperature, when sitting at a stop sign with it in gear the tach reads 250-300rpm. The engine may stall if I stay in gear and stopped for a longer period of time.

This may be (probably is) a simple fix but I’d appreciate some pointers on what to be looking for.
