My 2003 BMW 325 stutters and stalls. on 2003 BMW 325i

My car stutters when i first turn it on right about when it steps over the blue marker on the temp clock. if i drive with it stutters and stalls to the point where i have to park and shut it off and turn it back on, sometimes once and lately twice for it to work fine. If you have any advice please advise.
