Last trip to track - Nope! Coil went bad!?

Hey all!
Was going to make a last trip to the track and brave the 45-50 degree temps last weekend.
Fired up the Demon, took it for a ride, gave it a good checking over and parked it Friday night.
Went to fire it up and put it on the trailer Saturday - cranked it…….no fire.
Did it a few times, not one pop.
Pulled a plug - no spark.
My first thought was start simple……try the coil.
Ordered one from Summit, put it on tonight and FIRE! Damn thing fired right up.

Ive had the car on the road for a little over a year, bought the coil/MSD box and distributor about 3 years ago.

Question Is, - Has anyone randomly had a coil go bad?
It’s the MSD Blaster High Vibration 8222 which supposedly can be mounted any way due to its encased in epoxy.

Is there a better coil choice?
I’m afraid the original one went bad, when will the one I just put on go bad unless there’s an unseen issue I’m missing.

I appreciate everyone’s help ahead of time.

Thank you!

Wally.
