Lets summarise:
When the switch closes momentarily you want the 4017 and leds to run thru the sequence and then stop, display for 3 secs and go blank.?

You need a freerunning (astable) 555 to CLOCK the CD4017 (LED rotation), and a monostable 555 to start & stop the LEDs via the RESET pin.
 
Have you tried a delay IC such as 4047 or 74C123? It may be possible to interface either IC to the 4017 or 555 to activate the LEDs for the time you specify.
