There is a fuel cutoff switch on the passengerside floorboard, towards the right kick pannel, there will be a little red button on top of it, check to see if that is tripped, also when you turn the key to the on position listen to see if you hear the fuel pump prime up, just a short buzzing noise from the underside of the cab, if you dont hear it, that is a good indicator that your fuel pump maybe bad, i would also check the pressure at the fuel rail, chrome or black colored bar located near the fuel injectors.

Its normal for the pump to run for three seconds then shut off if the car engine is off. . This indicates that the fuel pump turned on and the pressure did reach specifications. If the pump did not reach pressure the pump would continue to run, You need to check for proper pressure with a gauge. If tthe pressure is ok then you have another issue like an ignition module or crank sensor if applicable. You may have to drive the car with the fuel gauge hooked up to see if you still have pressure when it dies.. I know you said you replaced the pump already but do you have the same issues as before you replaced it. This would indicate which direction you need to go now. If the same then its prabably not the pump.

If yours is the v6 2.5 the tps is adjustable and you can turn it up and down. On my mazda it acted like it was in the fuel system and i ended up replacing the distributor.

engine wiring harness upper and lower could be degraded, coil could be bad, throttle positioner, fuel distributor could be bad and depending if its a half year car and you have an OVP that could be bad. Also after a full tune up have someone adjust the duty cycle.
