When the engine stalled, would it crank over afterward or just not crank? Do the head lights appear bright? The battery cable end sounds like it has a "non original" battery cable end. Start there first it needs to be fixed if it is not the problem it is a potential problem. Bad battery connections cause a voltage drop which could cause a stall or no start condition. If you hear the pump run it could still be an intermittent problem but if the engine wont start and you hear it run, I would verify fuel pressure at the fuel rail in the engine compartment and check for spark. Autozone have some popular workshop manuals for free on line once you register (for free) on their website There is also a company that independent auto repair shops buy their information from that the same information inexpensively to do it yourselfers. The information is year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... Alldata is very easy to navigate
