Could be caused by an idle air control motor being carboned up- it might also happen if you turn the a/c on or making a hard turn with the a/c- basically anything that loads the engine up- try sitting in the driveway and loading the engine up- if it dies start it again and try holding the gas pedal down just a little to see of it helps- if it does try cleaning the idle air control motor. This could also be caused by a fuel pump or maybe an alternator problem but most likely the idle air control motor. good luck and let me know what you find
