all of my power steering fluid dumped out in one big event (in the driveway). what should i look for? what's most likely problem?

What is your question?

vehicle was in driveway. i started it to put it into the garage and suddenly couldn't turn the wheel and wheezing noises coming from engine area. Puddle of pink fluid on the ground. hoping it's just a hose or connection. pump was replaced a year ago. 154,000 miles.
