Welcome Scarlet! Good that you're enjoying your Cougar, even with the fuel issues. Sounds like it might be a fuel pump, or even the gradient the car is parked on. My Mother's Focus (different car I know) has similar issues when parked on a hill and low fuel it'll have trouble starting.
Not much of an update from me, but I paid off my car so I now own it, not the finance company! Yaaaaaay! Installed a set of HID's to celebrate as well
