Is my Boxster ****ed?
 

75mph on the interstate and the red LED on my temperature gauge starts blinking.
Before I can get to the next exit my check engine light (CEL) starts rapidly flashing.
I put it in neutral and coast off to the shoulder and the car shuts off and every light on the dash comes on.
I wait 30 minutes but the car will not turn over again, but it really wants to. It says "vrig-jig-jig-jig-jig-j-j-jig"

Please tell me what's wrong with my Boxcutter? Tell me what to do, I'll do it. I will jack this thing up and pull out whatever you want me to. I will buy parts, I will replace them-

(Please don't tell me I have to replace the engine. I will hunt you down and kill you. haha, just kidding... well not really)
