Starter?

Check for power to the starter with the key in the start position. If you have power, then I would say you need a new starter.

Are you rocking it in gear?

Sounds like you have a starter and/or flywheel ring gear problem.

Keep in mind that free advice can frequently be worth less than you pay for it.

How do you know you had "full power"? You need to check for power at the starter. Otherwise it could be a lot of other things causing a lack of either supply voltage or start signal to the starter. You need to check that the starter is getting proper supply and signal with the key in the start position.

Sounds like a starter problem or cable that leads to the starter. There are contact points on the start just like on the battery. Check those and tap (Not Smack) the side of the starter with a hammer. The starter might have binded up.

There is a common problem with mopar starters in the washer / fork contact by the starter solenoid ( sorry my spelling and technical description suck but I know what I am trying to describe LOL ). Replace this washer when you find you have to click the ignition a few times to get starter to engage as opposed to buying a new starter.

if its your starter, it'll happen again, you just have to wait and see. or it magically fixed itself like they are prone to do.

Yeah right!!!! Unless you wanna work 40 hours a week!!! Geez!!!

Before getting too deep here, start off with the simplest of basics and go from there... you need to first remove both battery cables and clean them and the battery posts with a wire brush. IF the battery is good like you claim it is, the usual cause for this problem is nothing more than a bad battery connection.

Don't just look at the battery connectors and pronounce them ok either, you really need to remove and clean them with a wire brush and reconnect them solidly before suspecting anything more complex or more expensive.

Getting Savvy...

When you have a choice, buy American.

My TJ and esp the Grand I had were real picky about this. Clean connections and make sure they are tight.

and visually inspect the cables themselves. if the insulation looks old/rotten, or you can see rusted wires replace the cables.

I'm with Jerry on this one, the intermittentness of the problem screams connection issue somewhere.
