1992 Honda Accord stall when warm

I have 92 honda accord lx Automatic every time it gets warm it stalls when u come to a stop. If u do gett it going on a long stretch take your foot of the gas and the reaply your foot to throtle u feel a hess itation or like a dead spot before it reacts? Tried idel speed motor and a noth icnitor no luck still the same. There is no brokage in exaust /at idal it takes gas fine no hesitation. It started with just a rough idle at a stop, then stalled every now and then now at every stop it stalls? The car gets about 2000 miles a year for last 4years but new driver and it get a regular run everyday.
