fuel smell in car and stalls sometimes? HELP

i have a 93 taurus 3.0l .. car was givin to me.. inside the car you can smell fuel.. seems to be worse when the tank gets low.. recently i was parked with the car running for about 20 min, when i went to take off the car stalled.. waited about 30 min and it started up no prob and drove fine.. the next day i ran some errands after about an hour the car stalled as i was driving about 45mph. felt like i was running out of gas, but the car has 3/4 tank.. let the car sit for about 10 min, started back up no prob. I drove about a mile and it stalled again. Had to do this about 5 times so could get home with it. The car will start up no prob but afraid to drive it and get stuck. Dont know if the fuel pump is going bad,or maybe the fuel pressure reg is bad.. anyone know how to test to see which is bad
