While riding my 04 marauder 800 it died. It will not not even attempt to crank now. I tested the bat. and it is good. What has shut down my bike??

Clogged fuel petcock or dirty fuel filter.

Question edited for clarity and typos.

I had a similar issue on a Kawasaki Z1300. It was caused by a fuel line that was routed very close to the rear of the cylinders. When the engine heated up it caused a vapor lock, so basically a gap in the fuel delivery. Backfires can also be caused by weak fuel delivery.

possibly, it might be the kickstand safety switch is sticking!

Sounds electrical... typical coil issue.... get hot... quits... cools off..runs until it get hot again. a well equipped shop can load test the coil..

Most bikes require that your battery be in goo condition in order to run. They actually use the battery as part of the ignition circuit. So if your battery is completely dead it will drag your ignition circuit down.
Recommendation: Remove your battery, charge it and/or get it tested.

Secondly, if your battery checks out as being good, the only other thing I could think of it being is your charging system. That being comprised of a stator and a voltage regulator. These are semi expensive parts so, once you get past the battery check, I'd advise you to either get a manual for your bike, and some testing equipment (if your mechanically inclined), or take you bike to a reputable cycle shop and have them check it out. This way your not replacing good parts trying to track down the problem.

Good Luck.

ITS FUEL QUALITY YOU NEED TO CLEAN OUT YOUR TANK FUEL LINES AND CARB AND USE HIGHER OCTANE FUEL
