On older vehicles that have sit, the fuel system is a major source of problems. Here is a summary: My truck kept stalling/loosing all power whenever it warmed up to normal Temp. In the past, this mix of gas and air was provided by a device known as a carburetor, and because cold weather makes it harder for gasoline to evaporate, the carburetor could end up releasing a gas-air mix that would end up causing engine problems.
