Will not run

Since buying, I have replaced the fuel pump, PCM, eight plugs, wires, both coils, and related gaskets. It ran super fine for approximately four weeks, then the check engine light came on. Autozone said AIC. About a day passed and the check engine goes out, that happened one more time, then light goes out again. But running okay without warning it sputters out in a parking lot will not crank at all. Replaced IAC, now turnover starter and it tries to run for a second then it quits. Help!
