2 Check Engine Light On problem

Failure Date: 08/03/2019

For seemingly no reason, the vehicle will restart and stall while driving and multiple warning lights will illuminate. This has happened while driving slow, fast and while turning. When this happens, I need to immediately pull over and restart the engine. The check engine light turns on and indicates an abrupt voltage change issue, but soon turns off after a few power cycles. This started to happen more and more often, and more recently, I had the car not able to start as if the battery died. All my electrical components, such as headlights and hazard lights shut off and after about 10 seconds, they all turned back on and running normally. At this point my vehicle started up again just fine. This has nearly caused an accident a couple times and no mechanic has been able to diagnose the issue yet. Although, this issue seems alarmingly close to a recent recall that was announced for 2018-2019 Mazdas relating to a software issue that causes unexpected engine stalling relating to the fuel-saving cylinder deactivation technology. Unfortunately, even though my vehicle contains the same technology, it wasn't included on this recall list.
