That fuel pressure drop sure looks like your problem. Seems like maybe electrical problem, but that is were I would continue looking. Probably going to need a scope. If you have to take in to have someone that has done electrical toubleshooting at least you have gathered some good information to go on.

 

I changed the crankshaft position sensor and it hasn't died yet! I'll post back if it ends up drying again but I sure hope not. I've read several forums with the same problem but no answer. Here's a how to for anyone else with a similar problem. I'm no pro but maybe it can help someone.

 

Awesome. Glad you were able to get it sorted.

 

Maybe an intermittent fuel pressure regulator at the pump???????
