Default Stalls when engine warms up

Ok so I need some help. Im have a 2004 LB7 210k 50k on new injectors. No mods, Ca smog ready(EGR,cat ect). All stock.

It will start fine when cold.
It will run normal in tell the temp reaches about 180 then it wants to stall out like its not getting fuel but will start back up right away. Around 190 it dies and will not start back up with out cranking for 30 seconds to a min. No check engine light comes on.

If you have any advice Ill gladly take it.

Added when it starts to stall the door lock actuators lock, unlock a few times.

Check the codes, it may be throwing codes which do not show a MIL.
