WIDNES threw it all away after battling back from 12 points down to equalise in the South Lancs-Cheshire One.
The game was there for the taking but Wids failed to respect possession enough in some of the set pieces and Burnage made them pay.
The visitors intercepted a pass to score a converted try from a Widnes move that had broken down in midfield before a late penalty sealed their win.
This was a disappointing result for Wids whose mini-revival had seen them pull away from the lower reaches.
Lee McDermott's men were also left to rue a slow start as the South Manchester side had two tries and a conversion on the board in the first 15 minutes.
Eventually, the home side found their feet with a try from centre and man-of-the-match Gareth Riley.
Andy O'Neill's conversion reduced the arrears to 7-12 at half-time.
Ten minutes into the second half, prop Liam Wilde combined with Tony Fretwell for scrum-half O'Neill to score one of the best tries seen at Heath Road all season.
Widnes take a break from league action this weekend, but on Sunday entertain un-beaten Liverpool St Helens in the Lancashire Cup (ko 3pm).
Broughton Park 2nd 28 Widnes 2nd 3: Widnes turned in another good effort in this top-versus-bottom clash.
There are just three games left and Widnes' relegation in the Miller Homes League was confirmed some time ago.
But captain Derek Dyer remains confident his battered and bruised side will return better and wiser for their experiences this season.
The visitors briefly held the lead when Chris Leedam kicked a penalty.
Broughton Park's class and extra fitness showed with three tries in the last 15 minutes.
Wids' Ben Hazzard and Rob Critchley were outstanding while Simon Alderson and Mark Whitfield returned from long injury lay-offs. Eagle 2nd 28 Widnes 3rd 24: Widnes fought back from 14-0 down and were unlucky not to defeat a side pushing hard for promotion.
The visitors appeared to be half asleep in the first quarter and quickly conceded two soft tries.
However, Rob Council set up captain Andy Rigby for a try which was converted by Geoff Owens.
Eagle came back before Joe Clark supported a midfield break to race 60m for his fourth try in as many games.
Owens' goal cut the deficit to seven points.
The home side scored a great individual try early in the second half but, from then on, Widnes piled on pressure.
Vaughn Evans stretched over and Mark Housley went over from a mix-up in Eagle's defence.
Dave Breeden and Graham Riley were both a tower of strength for the visitors who entertain Birkenhead Park on Saturday.
