Vehicle starts and idles but stalls after warm and put in gear. Any ideas ?

Does it have an EGR valve? If so, disconnect the vacuum hose from it an plug the hose then see if it still does it. If not, bad EGR. EGR valves can test good but be bad from a weak spring. This is the only way I've tested them that I know for sure. N it's quick n simple.

Hi thanks - no egr on this
 
Sometime s this happens when your torque converter goes bad
I expect it to be a vacuum leak Bad gas or bad ground or no accelerator pump
Hi thanks - can’t find a vacuum leak gas is new tank has been cleaned and lines replaced and the accel pump seems to be good. I’m wondering about that torque converter though - how can I tell if that’s the problem ?
 
Could be bad gas as Moparguy said. How old is the gas? It will run and rev but idle wants to stall.
 
Simple thing to check - carb to intake bolts. Make sure they're tight.
 
Does it have a catalytic converter?
Your symptoms
Sound like a clogged one to me
