SOURCE: 93 katana 600 wont start
Take one of the plugs out and hold it against the head while the engine cranks. You should get decent spark. If not, you have an ignition problem. If it gets decent spark, try spraying some starting fluid into the air cleaner box. If the engine starts up and runs for a couple seconds, you have a fuel delivery problem.

SOURCE: Dies in mid-ride
I HAD THIS PROBLEM. BIKE WOULD START AND IDLE NO PROBLEM. WOULD GET UP TO SPEED AND DIE. WOULD START AFTER SITTING. BIKE HAD BEEN SITTING FOR A PERIOD.
FIX:: REPLACED FUEL FILTER FIXED THE PROBLEM.
LOCATION::: TUCKED UP ABOVE VOLTAGE REGULATER RECTIFIER IN FRONT OF REAR TIRE LOOKING UP.

Sounds like a loose piece of crud in the main jet. Have you had the jet and tube above it out? It could also be a spark problem. See if you have spark when it tries to die ( put a nail in the plug boot and get it sparking 1/4" or so to the plug at idle then rev it up, it should continue jumping. I think that bike will also have mechanical spark advance on the rotor on the end of the cam. If the springs are loose on that the spark timing will be all over the map and can make it run intermittantly.
