'13 WON'T START UNLESS I TIGHTEN BATTERY CLAMP SAME NEXT START

While taveling I came to find my '13 93 (3.8) sedan wouldn't start. I went to the trunk and tried to see if a battery clamp was loose. I immediately got power and off we went...until the next stop where it happened again... and again. Tightening the positive clamp restores the power until... The clamp is as tight as I can get it. I hear an electric "snap" when I push the start button and everything goes dead. There is a momentary dead spot and thenthe engine starts. I'm wearing out my ratchet handle!

Fuse block is likely bad, intermittent open, you're hearing the arc.

On top of the battery.

I was looking at that yesterday and it felt "floppy". It was firm before that. Great response! I'm headed to Hyundai, extended warranty in hand. Thank you, thank you...

To Gunkk:
thanks again. I went out to the car (in daylight) and found that the nut at the rear of the unit was loose. This movement was the cause of my problem.
On our vacation trip when this first occurred we had a large container of water bottles placed upon this area. I thought it had broken the unit but...
Thanks
