Stop in for a cup of coffee

that is the whole problem it's intermittent, I can get on the highway and punch it RAAAAAA!!!! it runs like a beast and then the next time I step on the gas it will make a huge hisssssssssing sound and bog out. I drove it for two days with no leak and then it suddenly came back back today while on the highway

after it cools and is started again, its a 50/50 chance it will leak again

the other day it started leaking on start up and then a mile into the trip the leak stopped and all the power returned

It may be temperature related and only leak when cold....
