Exclamation PO335 car shuts off whenever it wants

In advance, thanks for taking the time to read this.

So my car has been an unreliable mess ever since i decided to go back to stock.

2005 sti is stock except for magnaflow axle back and k&N short ram intake.

3 weeks ago went from stage 2 to stock.

car currently throwing PO335

Suspect problem to be a lose ground or melted wire that is shorting out. Only Because Water temp sensor goes in and out (For over three months now so probably not a dying sensor) and Because Dccd has also gone crazy.


For those who want the full story read below

My ap wiped out my cu in the process of unmarrying it. Sent ECU to COBB they re-flashed it. Upon Arrival car seemed fine but started to shut off unexpectedly with no apparent pattern or check engine light. Twice while driving it car shut off and DCCD went open diff and started flashing but promptly turned back on. Seeing dccd light flash i connected ap to see if it would pick up a code. In order to read codes AP must be married. Married AP ecu = dead again. Waited a week for holidays and sent in ecu.

Naturally i assumed a problem with my ecu because everything seemed fine. Cobb fixed the ECU yet same problem.

Finally car gave me a check engine light and left me stranded. PO335 Awesome i thought. Drove to dealer replaced Crank Position Sensor. Car started right up! Driving it home it must down about 10 times (115 miles away)

One thing i should add is when i first installed ecu after getting it back from cobb. there was smoke and the smell of burning plastic coming from my down pipe area i assumed since i was putting my old downpipe back on it was just burning off the water/trash it may have accumulated from laying in my back yard for 6 months.
