stalling-some times
 

a few months ago I was riding and all of a sudden it had no power and stopped and stalled.thought it was a coil but it started back up and every thing was good.today I was riding for maybe three minutes and when I gave it gas it was dying .I let off the throttle and it was fine.my air cleaner and carb are clean.i don't know if it sounds like a loose connection or is something going out.if it is a connection where should I look

Check your plug and make sure it's not running lean. The stop and stall could have been a soft seize from running too hot/lean and can ruin your cylinder and piston.

I was thinking the same but the plug is chocolate brown

found the problem it was the intake, came off the boot.i guess when I cleaned the carb I didn't have it on all the way.its always the simple things over looked.it idles good now and better accelaration
