No. If you are running good with the O2 sensor wire unplugged, your problem is in the lambda system. If you unplug the Impulse coil your engine will not run.Originally Posted by Iceguy

Ok, I found that one first. I remembered you said if I unplug the wrong one the car would stop. It did. So I replugged that one and searched for the other connection. From what I have read about the lambda system is only for emmissions. It wont hurt the motor to not have it connected ? I live in Florida and dont need to pass inspection.

No - not fixed. It just ran 3 min and shut back off.

So did that first wire (not a blue wire) fix it and the O2 disconnected will not fix it?

It doesn't run with either or both wires disconnected. After I disconnected the first wire it ran great - that day. The next day I start it - 3 min later shuts off. The same with blue wire. Disconnected it yesterday, the rest of the day it was running great, but start it today - 3 min then dead.

I'm thinking Johnathan may have been right about the fuel at this point. Maybe try this:
Next time it runs then quits, immediately see if there is pressure at the air plate. If no pressure, check the fuel filter. If so, quickly push it down and release it (dumps some fuel). See if it then starts right back up rather than having to let it sit a while....

Hey Iceman,
Any chance you've got a bad batch of gas in your tank? Either old gas or maybe a fill up at a station with either stale gas or water in it? Have you emptied and cleaned the tank since you've owned it?
Good luck. ~ Slider

If I missed it I apologize, but sounds like crud building up on the pick up filter in the tank.

Make up a jumper for the RPM relay. I have seen many of those cause intermittent engine stoppage. It's just that your first post seemed to repeatable timing to be that problem. Your jumper should connect the large brown wire to both the white/purple wire and the double yellow/red pin.

I almost spit water at my screen. 10,000 RPM would be a smidge over redline, methinks.
