Have you checked spark?

Kill switch?

Does it have a side stand switch?

 

Alternator?

 

Don't know if it will help but on my 01 750 the key cylinder has a diode in it and the diode burnt up or sumthing and its a type on anti theft where if the ecm doesnt receive the correct voltage after the volts pass thru the diode it wouldn't let the ignition system produce spark. Wouldn't prime the fuel pump. All it would do is crank over all day long. Swapped key switch and bam fired right up

 

ok so when i changed the plugs i poured seafoam down in there and let it set for a couple days. Just tried to crank it and it cranked right up. Check for firing and the coils are firing like they should be, and the kill switch has no corrosion. Let it idle for about 10 mins and ran fine. Shut it off and it cranked right back up. Could of it just been the plugs and all that carbon and trash down in the holes to cause it to cut off while riding and not crank back up???

 

My votes on bad connection somewhere.

But when it died on me all the lights were still on

 

ok new problem today. cut off while riding today. blew the ignition fuse and tripped the breaker. reset the breaker, replaced the fuse and it just tried and tried to crank but wouldnt start up. also the lights for neutral and oil wont come on.

 

Get yourself a multimeter and a service manual, and test the electrical system components (stator, R/R, battery, and charging system while bike is running). Test the connections, check the wiring harness, etc. Don't throw money at the bike until you have found the problem, then fix it.
