You already got the extra life before the head gasket,cylinder head or engine needs to serviced / rebuilt.
Blue Devil and products like are only temporary fixes and are only used once, after than then it is time to fix it properly, this time it sounds like the head gaskets may have blown into the combustion area possibly between the cylinders, so the compression is just swapping cylinders.
its most likely as tennisshoes said but could also be electrical stopping it from firing the fuel injectors or spark plugs
