Nigel Bond kept his hopes alive against Alan McManus as he hung on to trail 9-6 before the session ran out of time.
Bond won the final three frames of the session in a battling display but the match contained little excitement.
Breaks of 57, 117 and 65 kept the qualifier in a game he looked certain to lose heavily after McManus moved into a 9-3 advantage.
After over six hours of turgid snooker, the players will return on Tuesday to finally end their marathon contest.
