Some more info. My father said the battery cables looks good and are clean. And he said now he is getting issues with the radio as if it is re-setting. He has also had the key get stuck a couple of other times in the ignition, and has said it is getting harder to start at times. It is cranking well, but seems as though it is sputtering.
I still haven't had a chance to make it over there to look for the grounds, but it sounds like that may be it.
Thanks again guys.
