The problem you are describing could most likely to be a fuel pump control circuit. Here is what I had wrote in my old post:
The problem sounds like fuel pump switch inside air flow meter. First, open the diagnostic box and jump the Fp and B+ terminals. Start the engine with jumper connected.If it runs normally, check connector on air flow meter. If OK, check the circuit opening relay near engine ECU. If still good,then it is possible to adjust the fuel pump switch inside air flow meter. To get access to the switch, you need to remove the black plastic cover on top of AFM.
For this case it turned out to be loose connector on AFM.
