mower won't start when hot

[paulinwoodinville]

I have a generic (PowerPro) gas mower with a 5 HP Briggs & Stratton manufactured in 1995. It must have sat in someone's garage for most of these years because it looks like it's only a few years old. I picked it up at a garage sale. It ALWAYS starts on the first or second pull even after sitting for 5 months over the winter, and runs perfect. The problem is that it's impossible to restart once the engine is hot and I shut it off. I have to let it sit for hours, usually overnight, it then starts on the first or second pull. This pattern has been consistent with each use for the last 2 seasons. My wife is tired of hearing my excuse, "the mower won't start" and wants me to spend $500+ for a new mower. HELP!!

May sound silly, but change the spark plug and test..
