You have slowed down.
need more info. does it shut down while driving? shut down on decelleration? acceleration? does it sputter or is it like the key was shut off? is there a loss of power before it happens? does it restart right away or do you have to wait , and if so, how long? is the yellow "check engine" light on: Does it stall every ten minutes until it's fully warmed up?
