A5 2010 switches off from the blues

[#TruthSyrup™️]

Hey guys, kindly help me here. I have an A5 2010 a real beauty it is. But I don’t know what the problem is because this car would just switch off sometimes while am driving, imagine even when am speeding on a highway and it just switches everything off and I have to put back the gear to park then restart to continue my journey. And I also get the EPC error message whenever I do a good pick-up speed, what’s up with that, it’s supposed to be a flipping sports car for crying out loud!!🤦🏾‍♂️
 

Thanks for you help in advance before this car kills me in highways 🤜🏾🤛🏾
