This is my new E-TEC 200 HO which was the repower for my Ranger 200C.
At idle, after about 15 minutes of run time, it burps, stumbles,
hesitates, hiccup - however you want to describe it. Everything else
appears normal. It will do this about once every 5 to 6 minutes of
run at idle or trolling speed.

At about 40 minutes run time, it will light up all the warning codes
on the gauge, but not default into SAFE mode.

Within 10 minutes the above event, individual trouble codes will
appear one by one and the engine will default into SAFE mode, but if
you shut it off, turn it back on, the engine is normal until it
happens again.

Interesting part #1 - the total time between failures decreases -
which is to say that the failures occur in a shorter time span - for
instance, first one at 10 minutes, next at 8, next at 5, etc.

Interesting part #2 - it will default into SAFE mode without any
codes. :)

Believe it, it had a bunch of people scratching their heads until some
bright tech at BRP came up with the answer.

So, what 'cha think?

That's a good one. Since everything is controlled by the EMM, I'm sure that
was checked out and/or replaced, and that the problem continues. That leaves
the sensor circuits as they are the ones that report to the EMM and impart
information. Since all the warning lites illuminate on the SystemCheck
gauge, I would guess that the common link for all the sensors is at fault.
The 5 volt reference voltage is the only thing that is connected to all
sensors, so then it is probably a bad connection, intermittent short, or
something causing it to fluctuate or change value.

Along another line of thought is that there is an AC component leaking into
the various DC voltage circuits. There is also a possiblility of wing nuts
on the battery or loose connections, but you've been around too long to have
that on your boat.

I don't have a manual with me, so this is only from the top of my head. What
was the final outcome?
