Altenator?
I'm no good on the spanners so take whatever I say with a pinch of salt. I'm only suggesting this as I had the exact same issue with my WR450. Started to get dodgy on the button on a ride out in the Peaks. Then would only kick (fecking 450 needing to be kicked!). Then dead as a dead thing. Altenator was goosed. Bought new OE altenator (not cheap), fitted and job done.

I would say test the battery for power, and the altenator as it might not be giving you a good enough spark

When you say it didn't like starting on the button, was it turning over? Is it carb or fuel injected? My WR is carb and can be temperamental an its just down the idle screw on the carb, the crf is a race engine so is quite highly tuned there could be a specific starting method from cold?

Get a new battery and a plug wont hurt.. then test the charginging system and all the earths..

Had a quick search on the tinterweb and this is a common crf problem with varying answers, valve clearances seem to be high up there. Also it says make sure the stroke is at top dead centre with the kick (i know from experience this can make a difference) push the kick all the way down let it up and push it down gently till you get resistance thats top dead centre. Give the throttle a twist 3 or 4 times to prime it then try it without the choke prime it again and then use the choke and see if it will fire. Its worth a try before you spend any money.

Charge the battery, then try it, it could be an electrical fault discharging the battery
