Stressful position (3,4)
I believe the answer is:
hot seat
'stressful position' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for hot seat that I've seen before include "Position at top" , "Position of full responsibility (colloq.)" , "Position carrying full responsibility" , "Eat host In position of person with difficult responsibilities." , "Situation of responsibility or danger" .)
