Fauzi opened the scoring in the 33rd minute to put his side in front, before grabbing a second on the stroke of halftime to give them a comfortable lead.
And the Crocs simply imploded after the break as Tok Gajah went on to record an emphatic victory with further goals from Boris Kochkin, Hafiz Kamal, R. Gopinathan and Fauzi, who capped off a memorable night at the office with a third - and his side's sixth - two minutes from time.
The result was enough for Pahang to remain top of Group D, three points clear of Sarawak and Selangor, who picked up their first win of the campaign after beating T-Team 1-0, courtesy of Safiq Rahim's 80th-minute penalty.
The hugely-anticipated Group B clash between Super League winners Kelantan and Premier League champions ATM resulted in a 1-1 draw. Armed Forces striker Marlon Alex James, who finished as the top scorer in the Premier League, broke the deadlock in the 55th minute but the game had to be suspended after home fans disrupted the proceedings by throwing objects onto the pitch.
Nigerian defender Obinna Nwaneri equalised in the 87th minute but despite the addition of 17 minutes of injury-time, both sides were unable to find another goal and had to settle for a share of the spoils.
