Thanks for the help, but it still won't disappear after ten seconds, and it doesn't get slower.
Here's my code with your code inserted
REM ---------------------------------------------
REM |Veritas Lentation Inducing Game Version 1.0|
REM ---------------------------------------------
REM Set up sync
Sync On
REM Hide Mouse
hide mouse
REM Load target and mouse
load image "lentation target.bmp",1
load image "mouse.bmp",2
REM Make target
sprite 1,RND(620),RND(460),1
sx=sprite x(1)
sy=sprite y(1)
rem records the timer() value
a#=timer()
rem 10 seconds
b#=10000
REM Game Loop

REM Declare Game Variables
x=mousex()

REM Create mouse cursor
sprite 2,x,y,2
REM Collision and click detection

a#=timer()
sprite 1,RND(630),RND(470),1
sx=sprite x(1)
sy=sprite y(1)
endif
rem checks if current time-time at the beginning = b#
if timer()-a#=b#
rem replace this with your repositioning code
sprite 1,RND(630),RND(470),1
sx=sprite x(1)
sy=sprite y(1)
rem keep this at it takes off 0.5 seconds from the time and resets the
rem variable a#, this bit also needs to be in the if clicked=true part of your code.
