2004 Automatic 307 Gas Unresponsive Die Stops

As I mentioned in the subject, while driving on the road in my automatic gasoline vehicle, the throttle became unresponsive and the speed dropped. The vehicle then stopped. When I ran it again, it did the same without taking 10m. My speed was slow because there was traffic. When the road opened, when my speed was in the 70's, the gas became unresponsive again and the speed decreased, but the gas did not stop before my speed was completely cut off. We saw the map sensor error in the error code, we cleaned it, but after working normally for a while, the same situation happened again. The vehicle fell out of traction. Sometimes the revs don't go over 30 and my speed stays around 50km. If I put too much pressure on the gas, the car comes to itself. I can't climb hills in D position anyway. I have to take it to manual and get out of 1st gear. Where do you think I should focus? Have you ever had a situation like this before?

It's been a long time, but I'm waiting for your information and help. :)

Good forum everyone.
