The Seasiders were unable to back up their scintillating 6-1 win over QPR at Bloomfield Road after being comprehensively beaten by Coventry City on their own patch.
Jerry Yates had levelled for the hosts when scoring his 11th league goal of the campaign from the penalty spot with 10 minutes of the first half remaining.
However, despite cancelling out Ben Sheaf’s opener, the Sky Blues restored their lead on the stroke of half-time when Curtis Nelson put the ball into his own net.
Kyle McFadzean and Matt Godden then wrapped up the points for the Sky Blues after the break.
It means the Tangerines, who have won just twice in 21 fixtures, have got it all to do if they are to save their season and stave off relegation to League One.
Mick McCarthy’s men are four points adrift of safety and have just eight games remaining to rein in the likes of Cardiff City, Rotherham United and free-falling QPR.
Blackpool kick things off with a Lancashire derby against rivals Preston North End at Deepdale on April Fool’s Day, as the season recommences following the international break.
They also face the Bluebirds and fellow relegation-candidates Wigan Athletic — who were hit with a three-point deduction on Monday — in two of the three games that follow next month.
