Once it starts sputtering carefully pull a spark plug wire off (it can shock you) and see what happens. It sounds to me like you have an ignition module issue that once it gets hot it is grounding out and then when it is sputtering it is because you are running on one cylinder

Runs good until hot chokes itself out or runs out of fuel engine reavs high then for 3 or 4 times then cuts off

sounds like the coil is breaking down at high temperature. make sure the engine is not covered with grass clipping and dirt. replace the coil. i think this will solve your problem

Have a kohler 27 on scag turf tiger the engine will turnover then the starter begins to click and will not start any suggestions

Check the oil for fuel in it. Oil will be really thin and be over filled. Take out the spark plug and see if excess fuel is pushed out when you crank it. If there is then the fuel shut off solenoid on the bottom of the carburetor is leaking fuel into the engine when it's not running.

Have a white garden tractor 54 in. deck elctric pto engine went bad got used 26 hp kohler courage for replacement it starts fine but it runs like it is slow in time and has no power and muffler gets cherry...

I guess this is the twin cylinder Courage engine, the symptoms you are talking about leads me to believe it is only running on one cylinder, this is why it has no power, and it is dumping fuel from the cylinder that is not running into the silencer which is then burns and increases the silencer tempreture. There are many reasons why it is only running on one cylinder, carboned spark plug, faulty ignition unit, burnt valves, bad pition, worn bore, i think your best line of approach is to fit new plugs, new air filter, check the fuel flow from the fuel pump situated somwhere on the engine, if that all fails get the local dealer to do a leak down test on the engine, this will give you a good idea of what the engine condition is like.
Good luck.

After starting car it sputters and white smoke from exhast. I drive the car for 5 min, sputtering the whole time, and turn it off - will not start until it is cranked and gas pressed for couple min. Then...

White smoke is usually from water and water will make the car splutter. Did you get water in your tank at some time. If you have water in your fuel, you will have to drain the tank and refill with good fuel. The engine will run fine once it is hot but if a lot of water goes into a hot cylinder it can cause a lot of damage.

Can you give me a ballpark figure on replacing a head gasket on a older Craftsman riding lawn mower...

there are many variables, since you didn't give any specifics. if it is an older, single cylinder, L-head engine, labor would be roughly 1/2 hour; if an older twin, L-head, about 1 hour; if it's a kohler, add about 1/2 hour; if it's a single, OHV, about 1 hour; if a twin OHV, 1 1/2 hours; if a kohler, add 1/2 hour. each shop has it's own labor rate. flat rate manuals will vary and are not realistic when dealing with old, possibly rusted or frozen bolts, which will increase the cost of repair. a new head gasket will usually cost between $5 to $30, depending on which engine you have. {some older craftsmans had a briggs laid sideways or an onan. these will require a lot more work and the labor would be higher]
