Coil Confusion

1970 Plymouth Valiant 318.
Electronic Ignition (brand unknown, installed by PO)
Orange ECU
Resistor .9 ohms
MSD Blaster 2 coil (PN 8202)
Primary Resistance .7 ohms
Secondary Resistance 5.4K ohms

Problem: Car just shuts off. sometimes at idle or under a load. will start after coil cools
Checked ignition wiring and all looks good.
Noticed the MSD Coil is VERY hot, can not touch.

Called autozone and they verified the specs on OEM coil's secondary resistance should be 10K plus ohms.

I thought my coil was bad, but the readings match what their website says.

Do I put a new (non MSD) coil on? or will that blow something up?

thanks,
Danny
