I had a late 08 MBP 15 once that did the same thing. I noticed it would continue to boot and not shut down as long as a key was pressed on the keyboard constantly. Actually it was more like a key had to be pressed every two seconds or so or the machine would shut off. I replaced the keyboard and that resolved the problem.
