Had this problem before.. guy from dealership came down plugged in his computer and said he “reset the fuel system” car ran fine for about two weeks and now it’s back not sure what the problem is any help would be greatly appreciated!
Put a pressure gauge on the schraeder valve on the fuel rail (passenger side front of engine). Tape gauge to windshield. Crank engine. Fuel pressure should stay approximately 5.1 Bar. If pressure drops and engine quits, check fuel relay, then fuel pumps, then fuel filter. EDIT: just noted you have an '06 which has two relays (one per pump) so reduces (but does not eliminate) a bad relay causing the failure.
If engine quits while maintaining ~5.1 Bar fuel pressure, the problem is likely a sensor feeding the ECU.
Ok so update on the situation. I replaced the fuel pump relay a few weeks back and have been testing the car. No problems at all so far seems to have done the trick! Thank you both for the help!
