I have jeep liberty 3.7 2003 just got it.After starting it up it runs for about 6 to 8 minutes and shuts off than starts up again no problem runs again for few minutes and shuts off again,My noticing is warmer it gets shorter it runs.When l drive it runs awesome but then it stalls on red light or when l slow down to make a sharp turn.I have cleaned throttle body and changed IAC,TPS,camshaft sensor previous owner changed spark plugs,air filter and put new batery in.I am about to change my fuel filter is there anything else that needs to be done.
