Sounds like your air filter needs to be replaced. hopefully thats all it is.
Are you in motion when it stalls? or sitting still?
There are 3 components to look at. Fuel, Air supply and spark.
Worn throttle cable can limit fuel also.
Fuel filter , air filter , fuel pump etc. The engine runs so you can eliminate spark.
With a little more detailed information you can narrow it down.
