Disciplinary problems played a part as Uxbridge let slip a chance to turn up the heat on fifth-placed Didcot Town.
Tony Choules dropped six players for breaking a curfew a week earlier away to Truro City and the Reds, in seventh, were held to a -1 draw by eighth-placed Gosport Borough.
Despite fielding a much-changed side including youth player Daniel Fleming, who made his first team debut, Uxbridge had plenty of chances to take all three points not least because they played the final half hour against 10 men.
The draw left them seven points behind Didcot Town, who have stumbled alarmingly in recent weeks, but games are fast running out for Uxbridge and Paulton Rovers in particular are much better placed to strike should Didcot continue to struggle.
Dave Thomas put Uxbridge in front with an 11th minute penalty after Kevin Warner was fouled by Lloyd O'Neill but Gosport hit back to deservedly level by half-time.
Justin Bennett headed narrowly wide and then fired another golden opportunity into the side netting before Thomas Chapman headed in at a free kick, five minutes from the interval.
Chris Robinson shot straight at the visiting keeper in one of few chances created by the Reds but after the break they began to cause more problems.
Lee Tunnell was a whisker away from regaining the lead with a flick and Gosport werereduced to 10 men when captain Glen Howes was sent off for violent conduct. The hosts had a penalty claim turned down when Chapman appeared to handle but as the game went on a draw always looked the most likely outcome, with substitute Chris Owens coming closest to a winner although his header was never really going to trouble the keeper. UXBRIDGE: Ross, Wharton, Bicknell, All-away, Dennison, Baptiste (Owens), Robinson, K Warner, Tunnell, Fleming, Thomas. Subs not used: Elford, McCarthy.
Goals, Uxbridge: Thomas 11 (pen). Gosport: Chapman 40. Attendance: 85.
* The reserves lost 1-0 at Eastleigh.
