Narrative:

Center directed us to fly direct to XXXX; a fix on the ILS into ZZZ. He also advised us to descend at our discretion from 17;000 ft to 4;000 ft; which we did. He then later cleared us for the ILS into ZZZ; which we acknowledged. A few minutes later he cleared us for the approach again; which we acknowledged once more. At this point; we were passing abeam the airport from the west; and the FMS sequences to runway xx and the aircraft began to turn to the right. The captain immediately selected heading mode to stop the turn and brought the aircraft back on course; the captain tried to re-sequence the FMS; however; he was unable make it fly the course we desired and did not want to be further distracted attempting to. Aware that we had a tailwind and were covering ground quite fast; the captain realized that we were about to go through the localizer course; having not been instructed to executed a procedure turn turn nor considered one myself; he turned off the autopilot and turn the aircraft inbound while descending. He did this at idle thrust; in attempt to capture the glide slope; and be stabilized by 1;000 ft AGL. Once on the glide slope; the captain reduced the descent angle significantly and increased power; however the aircraft got slow and the stick shaker was actuated momentarily; at which point we immediately initiated a go around. ATC had switched controllers; the new controller gave us vectors to re-attempt the ILS; which resulted in a landing. FMS sequencing to runway and initiating an uncommanded turn; associates increase in work load plus distraction attempting to rectify this. ATC clearing us direct xxxxx; clearing us [for] the approach with no indication of how they would like for us to do that. Neither briefing nor expecting to execute a procedure turn. ATC clear us again for the same approach; resulting in a very brief moment of confusion for both of us. Not asking for vector. Attempting to salvage the approach despite being high. Not applying sufficient power to maintain airspeed once on glide slope. Not abandoning the approach sooner and executing a go around earlier. ATC to be more specific if/when expecting us to execute a full procedure ILS. Flight crew did not expect vectors. Flight crew should ask for clarification if uncertain of ATC instructions or stipulations. Do not attempt to salvage the approach; ask for vectors if needed or execute an earlier go around. Proper air speed management; particularly when recovering from idle descent.

Title: Flight Crew executed a missed approach after the stick shaker activated.

Narrative: Center directed us to fly direct to XXXX; a fix on the ILS into ZZZ. He also advised us to descend at our discretion from 17;000 FT to 4;000 FT; which we did.

At this point; we were passing abeam the airport from the west; and the FMS sequences to RWY XX and the aircraft began to turn to the right.
