Hello, thanks for posting

This sounds like there may be a problem with the charging system, possibly the alternator is starting to go out, hard to tell if it will make it back 20 miles, depends on when this started happening it may make it back on battery power but I would recommend to try to have a repair faci;lity look at it or got to any auto parts store like Autozone, O'Reilly etc they can check the alternator and do so at no charge, this will prevent getting stuck on the road.
