At least the engine is turning, so it cant be that bad.
Your description of the initial symptom is going to be hard to decipher.
You are going to need diagnostic skills to work out what is causing this.
If no such skills, hopefully you have a friend who can assist.
Lastly, the local bike shop.
You see, it could be electrical (I am leaning in that direction),
Or fuel related.
First you will need a voltmeter, to test various electrical components.
Before anything else, first check the fuses....☺ï¸
