My 2000 would run and then intermittently not restart, let it cool down and it would restart.
The Battery was less than 10 months old. The positive terminal was getting hot enough to melt the nylon bag around the battery.
Although the primary connection to the battery was tight there are two other bolts that connect wires to the terminal that were loose. Tightening that connection eliminated the excessive heat (resistance) and haven't had a starting issue since.
