Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. It sounds like what you are experiencing is a loss of electrical power, even if it's temporary. This could be due to a loose connection of battery cables, or perhaps some kind of wiring or wiring connector damage under the hood. A careful inspection is needed to make sure what's going on can be resolved. Alternatively, you should also check the battery to ensure that it is able to be charged fully and is able to handle a load. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554.
