So, I was driving on the interstate going about 70mph, when suddenly, something somewhere on the car (possibly under the hood) popped and the car immediately died and i pulled over to the side of the road. After letting the car sit for about 10 minutes, i tried to restart it and it just wouldnt turn over. I'm not very car lingo savvy, but upon trying to start the car, it seems to crank, but just wont turn over and then it'll make this kinda exhale noise through the exhaust.

Anyone got any ideas??
I'm open to anything because i'm completely clueless
