1989 Other BMW Models FUIL

I'M HAVING PROBLEMS KEEPING THE CAR RUNNING IT SOUNDS LIKE IS STARVING FOR GAS, AS YOU COME TO A STOP IT WILL STOP RUNNING, WHEN YOU TAKE THE FOOT OF THE GAS, WHEN RE -STARTING YOU HAVE TO QUICKLY PUT YOUR FOOT ON CLUTCH AND PUT IN FIRST GEAR AND QUICKLY HIT THE GAS BEFORE IT STOPS AGAIN, IT STARED TO HAPPEN AFTER BELOW A 1/4 OF GAS REFILLED. IS THERE ANYTHING THAT WE CAN DO TO FIX THE PROBLEM.
THANK YOU
