I have a 2004 Mercury Sable which is just like it and recently had this problem. It ended up being the starter solenoid. I hope this helps you!

check the alternator fuse and grounding

one of the symptoms of a bad alternator is the battery light to come on so maybe you should check your alternator .

verify the belt tension-er is staying tight and not floppy around at higher RPMS,or the belt is not slipping ,have the alternator checked at higher RPMS not at an idle.the last is make sure the single wire little wire connector is tight
