I just replaced the XYZ switch the shifter indicator lights all work the Disco ran well. Then the next day while going to lunch the Disco shut down, then five minutes later it started up. Worked well untill I left work; it shut down three time on the way home. What could it be?

 

I don't know crap, but aren't repeated stalls like this often linked to the Crank Position Sensor?

 

RicknCody, same exact thing is happening to me. I installed the xyz switch, used the very expensive tool to set the switch, drove to work 40 miles everything was okay. When I was on my home, it stalled and I had the M and S lights blinking. After a moment it restarts. I hope someone can answer this post, because the closes dealership is 60 miles away. When I initially had the problem before replacing the xyz switch, it stalled, and from advice I replaced the battery, alternator, and switch. Its got to be something simple.

 

I just Purchased the crankshaft sensor; the parts manager said that is 99% of the problem, will install today. I bought the xyz switch for $125 from Roverland parts, look on line; it works just like new, easy to install. My electric is fine had it checked out at Advanced Auto.

 

Make sure you have the setting tool, cost $105.83 US dollars. I got one, saved a lot of headaches.
