Civic Stalling in Hot Weather

Hi i have a 1998 Civic Cx Automatic with 160k miles on it
The car has a hard time starting in hot weather sometimes and also
sometimes stalls when driving. When i stall the electric doesn't go off so
my radio is still on and everything but i have to go park and restart the
car afterward. There are no odb codes going off on the car and it's
recently had timing belts and fuel filter changed. I'm thinking it has
something to do with the fuel pumpish or something but i dunno. Any help
would be great. THX
