Suchao Nuchnum opened the scoring for Thunder Castle on the stroke of halftime, but Brazilian forward Diego Walsh equalised for the visitors nine minutes after the break.
However, there was to be no denying Buriram as they went on to claim all three points two minutes later when mid-season signing Anthony Ampaipitakwong found the back of the net.
Nonetheless, the defending champions are still a massive 14 points behind leaders Muangthong United, who cruised to a 2-0 victory over Chiangrai United.
Thai international Teerasil Dangda broke the deadlock for the Twin Qilins in the 48th minute, before Mario Gjurovski wrapped up the win when he doubled their lead three minutes after the hour mark.
Muangthong are also now ten points ahead of second-placed Chonburi after the Sharks were held to a 0-0 draw at home to bottom side TTM Chiangmai.
Wuachon United produced a stunning comeback at the Tinsulanon Stadium to beat Samut Songkhram 3-2.
Ivorian striker handed the visitors a two-goal lead at the break courtesy of a Bireme Diouf brace, but Wuachon captain Chaiyarat Madsiri pulled one back in the 58th minute, before Pichet Sadien grabbed the equaliser ten minutes later.
And with nine minutes left to go, the comeback was complete as Kirati Keawsombat found the back of the net to hand his side the full three points.
Sunday's other game between Police United and Pattaya United was postponed.
