Toyota Repair: 1999 Toyota Land Cruiser, toyota land cruiser, jumper cables

Question
Had to jump it this morning to get it to start, ran fine for an hour.  Turned it off
and tried a restart.  Nothing.  Runs fine after starting with jumper cables.

Answer
It sounds like the alternator is not charging the battery, start it again with the jumper cables and then disconnect the negative terminal on the battery, if the engine starts to die out and stall then the alternator is not chrging and should be replaced. If it keeps running then it's not the alternator and another problem exists, let me know.
