Shan soon followed his partner as he got caught behind off Nahid Rana. The Pakistan captain scored 28 runs from 34 balls.
Nahid dismissed Babar Azam and Saud Shakeel in his next two overs as Pakistan slipped to 81-6.
Mohammad Rizwan and Salman Ali Agha then joined hands to help the team recover, with the former scoring the bulk of runs to avoid further damage before lunch.
Pakistan had lost opening batter Abdullah Shafique and nightwatchman Khurram Shahzad in the dying minutes of the third day.
Prior to that, Salman Ali Agha took the final two wickets, including top-scorer Litton Das, to book Bangladesh for 262.
Khurram led Pakistan’s bowling charts with figures of 6-90, while Mir Hamza and Salman bagged two each.

Earlier, Bangladesh openers Shadman Islam and Zakir Hasan started the day with 10/0 on the board.
However, they could not add much to the total as Khurram Shahzad bowled a brilliant spell of classic pace bowling, leaving the Bangladesh batters completely bewildered.
In just the fourth over of the day, he took out Zakir with a skilful delivery on the last ball courtesy of an easy catch by Abrar Ahmed.
On the first ball of his next over, Khurram cleaned up Shadman with an inswinger. He missed the hat trick but he castled Bangladesh captain Najmul Hossain Shanto in the same over.
Mir Hamza also joined the party as he dismissed Mominul Haque in the next over.
Bangladesh veterans Mushfiqur Rahim and Shakib Al Hasan then fell prey to Mir and Khurram respectively with the scoreboard reading 26-6.

Mehidy was the pick of the bowlers for Bangladesh with a five-fer, followed by Taskin Ahmed, who bagged three wickets. Nahid Rana and Shakib Al Hasan shared two wickets between them.
From Pakistan, Salman Ali Agha offered a notable fight against the momentum-filled Bangladesh bowling attack with his 54 off 95 deliveries, laced up with three fours and two sixes.
Prior to that, Pakistan found themselves in a state of bother when Taskin Ahmed cleaned up their right-handed opener Abdullah Shafique a duck with an in-dipper.
Following the early hiccup, Masood joined Ayub in the middle and launched an astounding recovery.
The pair batted sensibly against in-form Bangladesh bowlers with Masood leading the charge.
Masood scored 57 off 69 deliveries with the help of two boundaries, while Ayub played a 58-run knock which featured four fours and two sixes.
For the unversed, the opening day of the second Test between Pakistan and Bangladesh was called off due to persistent rain here on Friday.
