My neighbor has a craftsman lawn mower with power driven front tires, 7.5 HP motor (If I remember correctly) aprox 3 years old
If it is cold starts great and runs great, but if you stop and try to restart it, then you can not get it to start.
Any Advise?

This sounds like a typical ignition module problem to me. Next time he mows have him run it until it gets hot 10-15 min. and then shut it off. Take out the spark plug and reconnect it to its wire and hold it against the engine block. make sure you are not touching the plug itself or you may get a little zap (then you'll know for sure if its working or not). Have him pull the motor over as if he was going to start it while you look at the plug to see if it sparks. If it does not spark then it is a bad ignition module. (Since it works cold you can be assured that it is not the ground wire) Write the model type and code of the motor down and look up the part on the internet or have a small engine shop look it up for you. then replace the module which is located under all of the plastic and metal gaurds. it is a u-shaped piece next to the flywheel. you will have to disconnect the ground wire from the old one and reconnect it to the new one. you can set the gap between the ends of the module and the flywheel at .005-.008 with a feeler guage. turn the flywheel by hand to make sure everything is ok and then put everything back together. (to test before putting it back together have a friend hold back the bail at the top of the handle to release the flywheel brake and lay the spark plug against the block as before. Spin the flywheel by hand as quick as you can and look for spark at the plug.)

Remember, lawnmower/lawntractor motors are made from aluminum- it expands and contracts. Is the oil changed regular? It could be a fuel /air problem - when its cold the choke lets it start, when its hot it doesnt need it. If it has a primer bulb, press it a time r two and see if it starts hot. It could be running a bit 'lean' - in that case id check the airfilter ( for excessive dirt - if really dirty, replace it) - then clean the carb.

Basic maintenance. Change the air filter and prefilter. Check your spark plug and make sure it hasn't fouled. It is more than likely the air filter/precleaner. Once they are clogged with dirt no air can get to the engine, causing it to bog, stall and not start.

check the air filter, i bought a craftsman not 3months ago and just used it for trim. In that time the air filter clogged completey, or so said SEARS, and they replaced it. Becareful if you take it to sears for repair. They will lie to you, they told me my blade was also worn out in less than three months.

try cleaning or replacing your air filter. If it is a Craftsman product, usually Sears will honor most maintenance issues, call them to find out . . have your serial and model numbers handy.
Good Luck

There are two small hoses that connect the primer bulb to the carburetor and these rot quickly. They are usually clear rubber/plastic hoses. Check them for brittleness/cracks and replace as necessary.

Check or install a new air filter

Did you try to prime it a couple of times when it is hot?
