assuming sparks are ok……sounds like fuel problem when was the carb serviced last ?

btw vent open on the tank try with the cap off suggestion… raise the tank above the engine a few minutes… if better probably bad pump…. all this if your engine is modified for pumping

if not ……make certain the tank is getting pressurized open the cap it should go psssst!

keep priming the button on the tank to see if engine runs better if yes …. you have a tank pressurizing problem keeping the fuel from being push up to the engine and refilling the carb.

(recent reported case of pressure loss was the small check valve feeding air pulses to the air nipple)
