This could be a few things...

Reed valve jumps out at me though. If it was absolutely fine then just cut out, i doubt it was a seizure, as you'd feel a drop in power before it happened.

Describe what happened when it stopped - did it just all of a sudden cut out, no loss in power and no funny noises?

My old RS did that to me it turned out to be a knackered plug, when I took the plug out it seemed fine sparked well but when I put it back in it arc'd the spark down the side of the plug

Also had a previous problem with my recifier so it wasn't charging the battery and eventually it cut out

if the bikes running and the battery dies i doubt it would cut out though, you can use them little bikes without a battery in them if you bump them, well you could on my rieju 50

lost compression = holed piston? did you put a shiny new exhaust on it not too long ago?

You shouldn't need much poking around to decide if the compression is low...as you dont have a kickstart, you should put the bike in gear and give it a little push. Easy option will be if you have a compression tester. But as suggested the RS is known for its siezures. I would just pull the head off and give the engine a quick look...its what all us other stroker fans do. Good luck Smile
