Wigan thought they had moved further ahead when Field went in again, but Junior Nsemba was ruled to have obstructed Leyland during the build-up.
It was a case of deja vu when Wigan touched down just before half-time through Kruise Leeming, but it was again chalked off for Nsemba obstructing Leyland in the build-up.
Josh and Jake Thewlis combined in the build-up to Tai's score after the break but Miski ran in with ease following some sensational work from French and Field to send him through as Wigan kept pace.
Keighran added a try to his points tally in audacious fashion - having initially failed to receive a high kick, it bounced fortuitously for Jake Thewlis, but Keighran regained possession when the ball bounced loose and he managed to run in from distance, but not before wrong-footing Matt Dufty on the way to cantering in on the wing.
Warrington ensured Wigan would have to work for the points, however, as Philbin touched down with an outstretched arm with six minutes remaining.
The Wire were not done there - Dufty atoned for the error which led to Keighran's score by battering his way through the Wigan defence and running most of the length of the field before offloading to Josh Thewlis who then teed up his brother Jake to touch down.
Golden point was not to be for Burgess' side, however, as Ratchford could not slot his kick through the posts, meaning Wigan held on for a victory which had looked like it was going to be much more comfortable before a frantic final five minutes.
