2019 CHEVROLET MALIBU Engine Problems

I WAS STATIONARY AT A RED LIGHT ON HIGHWAY 49 WITH MY FOOT ON THE BREAKS, AND WHEN THE LIGHT TURNED GREEN I LET MY FOOT UP OFF THE BREAKS AND THE CAR JUST SHUT OFF. I TRIED TO TURN THE CAR BACK ON, BUT STILL NOTHING. I WAITED A FEW SECONDS AND THE CAR STARTED BACK UP, SO I PUT IT IN DRIVE AND STARTED DRIVING, BUT WHEN I TRIED TO SLOW DOWN THE BREAKS WERE VERY TIGHT. FOR AN HOUR AND A HALF, I SAT THERE AND TRIED TO FIGURE OUT WHAT WAS WRONG WITH THE CAR. I FOUND NOTHING, SO I GOT BACK INTO THE CAR AND CRANKED IT AND THE CHECK ENGINE LIGHT CAME ON. I GOT THE CAR TO STAR CHEVROLET AND THEY DIAGNOSED THE PROBLEM AS THE BRAKE VACUUM PUMP. *TR

WITH UNDER 10K MILES ON THIS CAR, WE DROVE AN HOUR TO A BASEBALL GAME, THEN FOUND WHEN WE STARTED IT BACK UP, IT WAS ON REDUCED POWER. TURNED OUT TO BE THE THROTTLE BODY THAT HAD TO BE REPLACED. TODAY, WITH UNDER 17K MILES, MY WIFE WAS PICKING THE CHILDREN UP FROM SCHOOL, AND IT LOST POWER AND SAID "REDUCED ENGINE POWER" AGAIN. IF THIS WOULD HAVE HAPPENED ON THE HIGHWAY, IT COULD HAVE CAUSED AN ACCIDENT.
