PCM, wiring ??? (Engine shuts down) ???
Hey guys need a lil help on this. I recently repowerd my boat with a mpi 350. Now at any time, wether wot or part throttle it will just stop, never does it in calm water only a chop, but sometimes not, so I am in a wtf 
state. I checked all connections, everything looks good. IF ANYONE COULD TELL ME WHAT COLOR THE MAIN POWER WIRE RUNNING INTO THE PCM IS THAT WOULD BE A BIG HELP. NOT THE ONE THAT IS IN THE HARNESS, BUT THE ONE FROM THE HARNESS TO THE PCM ITSELF. I havn't been able to find it in the book. The computer has be tuned by ASM, I have heard good and bad on them, could the pcm be screwed up? It just seems to be a bad wire or short to me. Has anybody else had this problem, that could possibly shed light to this prob. As always thanks for your time..
John

What would CPS be..
I just went threw the complete harness in the engine compartment, checked all grounds and connects.. I am stumped. Hope it isn't a glitch in the comp. Started the thing up and wiggled the harness more then it could ever move and the thing still ran so hmmmm WTF
