car stalls when you come to a stop on 1995 Chevrolet Monte Carlo

car usually starts buts tends to stall when i come to a stop, and then is hard to restart. Is more difficult to start if front of car is downhill. Recently had fuel tank and fuel pump replaced. Could that be related?

Is the check engine light on? I'd get a scan test and see what's going on.
It runs good otherwise? No problems with hard accelerations?
