ANSWER: 

This is satan playing with your mind to get you away from praying for good!
Don’t listen to him and continue to pray the Fateha just once and don’t repeat, ignore the waswas and eventually he will give up on you in sha Allah. 

Kindly refer to the following link(s):

 

May ALLAH have mercy on you.I am a non Arab and while praying I concentrate towards the fact that I don’t make any mistake by mispronouncing any word in fatiha. But this concentration has made my Salah a burden I m afraid to pray due to the fear of mispronouncing anything and then repeating that word again and again till im not satisfied that I said the word correctly.PLEASE HELP
