WHY DOES MY ENGINE STOP WHILE I AM DRIVING

2005 Ford F-150 • 170,000 miles

2005 Ford F-150 XLT 8Cyl5.4L - Engine


When I am driving at speed my engine shuts off. 2 sec Prior to engine shutting off all the electronic gauges shut down. Vehicle can be jump started, but shuts down after driving or idling for 45-90 Seconds.
Also noticeable is a clicking sound in the area of the passenger glove compartment when the ignition is in off position. The clicking stops when break is pressed.
This symptom first occurred after I left the lights on for 4 hours earlier in the day. I Correctly jumped started the vehicle at that time. I was driving at about 45 MPH when symptom first occurred.
The Yellow air bag flickers on and off intermittently since the symptoms began. No other warning lights come on when engin is running

Sounds like low voltage from a failed alternator.

Have the battery charged and load tested and have the alternator checked for output
