Nissan Repair: nissan truck electrical, mass airflow sensor, haynes manual

Question
Frontier 2003 truck, no previous problems.  Driving down the road.  Dies.  No sputtering, engine running perfectly up until then.  Very well maintained, highway driving, regular oil changes, etc.  How do I troubleshoot electrical?  Battery is good, vehicle has power to run starter, but won't catch.
Thanks.

Answer
Hal,

I would check the mass airflow sensor and the fuel pressure to see if they are both working properly.  If the fuel pressure is down it will not run.  And, if the mass airflow sensor is messed up it will kill the car.  Get a Haynes Manual for the instructions on how to check the meter and to check the fuel pressure.
