Starting Help

Was driving my 07 ls coupe on the highway and it shut off and I can't get it to start again and had a large cloud of smoke come out of my exhaust what could it be and how do I fix it

What color was the smoke? Do you see any fluids leaking from anywhere near/underneath the engine?

Doesn't sound good. Did it make a noise before it died or did it just shut down?

White smoke is usually a sign of coolant burning. What is your oil level at?
