Hi, my name is Devin. I am an auto repair expert with the Car Genius team here at RepairPal. So sorry to hear you're having trouble with your vehicle.
When your Mariner loses all gauges, power windows, and the radio while driving, it's usually a sign of an electrical issue, likely related to the charging system. The fact that everything comes back when you stop and then fails again suggests an intermittent problem. This could be due to a failing alternator, a loose or corroded battery connection, or a problem with the ground wire. Since the battery light came on, the alternator is a very likely culprit.
Getting this checked out soon is essential because if the alternator fails, your battery will be totally depleted, and your car will not restart. I'd recommend having the battery and charging system tested to identify the issue before it gets worse.
