First, sorry for taking so long to get back with you. It's that time of the year. Anyway, the starter could check good even if it isn't. What needs to be done is the following:
When it doesn't start:
Have a helper turn the key to the start position while you check for voltage to the smaller wire on the starter. You should have 12v when it is in the start position. If you do, replace the starter. If you don't, check the starter relay under the hood in the relay box (power distribution box.
Let me know what you find.
