If it seems to be okay after it starts and drives a while, you may have a parasitic draw on the system. This is something that remains on, even after the key is off. A sticking relay or even a module that is not powering down can discharge a battery and be intermittent. Also check the glove box, under hood and trunk lights as well as those in the vanity mirrors.
