Is it possible to save a running program and reload next time ?

Can't you just use time.sleep to put your program to, uh, sleep?  For
example, time.sleep(10) will effectively pause your program for ten
seconds, making it use very few CPU cycles.  I don't know what
interface you have, but assuming you can pick up a button or a key
press, you can ask for a length of time, or just put your code into a
holding pattern:

def pause():
  paused = True
  while paused:
    time.sleep(1)
    if wake_up_key_pressed:
      paused = False

or with a gui:

paused = False

def pause():
  global paused
  paused = True
  while paused:
    time.sleep(1)

def onWakeUpButton():  #bind this to button
  global paused
  paused = False
