Stalling issues

Chevrolet Blazer 1993 K blazer 275365 miles
I have 1993 K Blazer that seems to stall when its hot and humid out... I have put new motor that now has about 60,000 miles on it... I have replaced map,sensor,egr,distributor,plugs,wires,coil,vacuum lines,fuel pump, fuel tank because it had a hole, vents in tank, fuel filter and many other parts and noone can still seem to figure out why i have intermittent stalls... It could be on interstate, at red light, stop sign it just will stall and start back up... It always seems to do it when it is hot and humid or just started because i didnt have this problem over winter or spring... Can someone please help me
