Let’s inspect the MagSafe charger:

Is the cord damage in any way? Cuts areas or bunched up anywhere along the length.

Inspect the MagSafe connector on the cord and the system socket are the contacts and insulator areas clean?

Use a cotton swab with isopropyl alcohol to clean things up. To clean the contacts get a new pink pencil eraser (still soft) to polish the contacts.

Get a new one directly from either a real Apple Store or online at the Apple web page Apple 85W MagSafe Power Adapter (for 15- and 17-inch MacBook Pro). Many of the ones on Craigs list, Amazon & eBay which claim to be real Apple units aren’t!
