1997 Questions for all other cars car chugging

Hi I have a 1997 Rover 200 1.4 i. Until recently the car was driving fine the car only has 39000 miles so this would be expected of it. One day I was driving and suddenly the car lost all power, the car would nearly cut out. The car would not accelerate with any throttle while this chuggung was taking place.I had to turn the car off and wait 10-15 mins while this took place. The car stated up after this and drove fine.
