1995 Mitsubishi Lancer acceleration

Hi there, my lancer idles low, it always starts first time. When first started it runs fine but after it heats up and i accelerate it start to choke like someones squising the fuel line and letting it go, it will do this and il loose speed and have to turn the car off and on again, that will get me a little bit further untill it starts again, i changed the fuel filter it was dirty as looked like a rust colour and ive changed the air filter that was in a bad way, what is my next step. Thanks jason
