You seriously need to A) calm down, B) stop expecting instant solutions to a car you know nothing about, and C) spit out more details.

Does it stall every time it rains? It also stalls sometimes when the heater is on? What other information can you provide?

My first instinct is an electrical problem, either battery or alternator. Do you have a voltage gauge? Do you know how to use a multimeter? Does the car have a hard time starting? Does it stall with the headlights on?
