Motor dies after starting off

Hello, my wife found out this evening after three short distances that the Check Engine lamp no longer runs out after starting. Besides, what is even worse, the car doesn’t work properly. When I start the engine, it immediately goes down again at the speed and dies off. Even if I give off soft gas. I noticed that the engine is quite hot (after about 3 kilometers all day), you can’t put your hand on it. But the temperature indicator is The thing makes me a little nervous, because I had a motor damage to this car before, but then during the ride, a short crack and that was it. This time the car starts for a short time. It is a 9-5er Bj99 with 2,0l 150Ps. I would be very happy about relevant answers and hope that it is nothing bad. mfG Jens
