Gosport & Fareham slipped to the bottom of London one south after a disappointing 26-15 home defeat by Maidstone.
Head coach Neil McRoberts felt his team only had themselves to blame.
‘We gave it away after getting ourselves into a winning position,’ he said.
‘The necessary killer instinct wasn’t there and we paid the price because of it.
‘We have to kill games off when we get ourselves into those positions.
‘But we came up short again in the final quarter.’
Gosport & Fareham led 7-3 at the break despite a below-par first-half performance.
Sam Foster scored the only try of the scrappy half following a kick-and-chase.
He also added a drop goal after the interval.
Although Maidstone hit back, a try from Tim Snowden put the home side ahead with 13 minutes left to play.
It was the visitors who finished the stronger, however, to take the honours.

The visitors conceded two soft tries before the break.
But they regained the initiative with a penalty try in the second half before surviving the late scare.
‘We were running on empty at the end,’ added Rhodes.
‘It was a terrific game played in a wonderful spirit.
‘The only disappointment was conceding five tries which kept them in it.’
