how do i find out why my car broke down and how to fix it

What is your question?

while i was driving my car made a noise under the hood, like something fell out... at the same time my car shutters & my tcs light comes on... then my car started to lose power & my oil & battery light's come on & i lose my power steering. then my engine stalls an now it wont start. but the lights & radio work fine. i just replaced the radiator, fuel pump, purge valve & some sensors. i also replaced my entire suspension pretty much... i do need to replace the steering rack though. i drive a 2003 Hyundai Sonata, with 184,000 miles. what would make my car do all that and how do i find out what is wrong when the dash lights dont come on now.

What makes this problem better or worse?

engine stalled and now it wont start.

How long has your 2003 Hyundai Sonata had this problem?

just happened
