Highlights - Murray loses to Fish in tie-break
Andy Murray's Wimbledon preparations suffered a setback as he crashed out of the Aegon Championships on Friday with a 6-4 1-6 7-6 (7-2) loss to Mardy Fish.
The match had been locked at 3-3 in the deciding set on Thursday when defending champion Murray was forced off court because of failing light at Queen's.
Both players held serve easily on the resumption to set up the tie-break.
However, the British number one played some poor shots and the American served out to seal a quarter-final place.
Murray will have no further competitive singles matches before Wimbledon gets under way on 21 June.
Murray eyes improvement for Wimbledon
The 23-year-old Scot is set to play an exhibition match next week but, having also gone out in the fourth round at the French Open, faces the prospect of going into the third Grand Slam of the year short of confidence.
The 23-year-old admitted he was not sure why he was struggling to produce his best form.
"I don't know whether it's focus or a lack of confidence," he told BBC Sport.
"There have a few occasions this year where I have made more mistakes than usual and had dips in form and that's something I need to improve.
"In terms of confidence I don't feel terrible on court and I don't feel like I am going to miss shots when I am going for them.
"I might just need more time on the practice courts to get my rhythm back.
"A lot of guys are struggling with the quick turnover from clay to grass. I can't expect to play my best tennis here and I will try to practise a lot and get used to the grass before Wimbledon."
Murray said he might even consider playing in one of next week's tournaments as he seeks to fine-tune his preparation before Wimbledon.
"It's not always the best thing to play a tournament the week before a Slam because if you do well you can go into it a little bit tired," he said,
Angry Murray rants at umpire
"There are a lot of options and I'll just have a think about what I think is best and what I want to do."
Murray's third-round contest at Queen's had been controversially halted at 2030 BST on Thursday.
It was a decision that had infuriated Murray, who felt Fish's appeal to umpire Cedric Mourier had been an act of gamesmanship after the American had lost three games in a row.
Having had a day to reflect on the incident, Murray said: "It's been tough, yesterday the conditions were difficult, it was very heavy on the court and blustery. We got stopped at a tough stage of the match and today I didn't play a good tie-break and I made some mistakes that I don't usually make.
"I think it's always good that both players have a say in what happens out there but nobody mentioned anything to me and that's why I was disappointed."
Fish, 28, the world number 90, said: "It was extremely dark last night, I told the chair umpire at 3-2 it was pretty dark, so we played one more game. I didn't do any pleading or anything.
"Today the wind's died down and it's much better conditions. I'm happy obviously, but when you can't see the ball there's no point."
