Doug,
There are posts on this. I have a 2008 Ridgeback and I can tell you that it is important to have a good clean battery connection, good clean ground to the transfer case, and a good path to the ignition switch. All of this is important assuming your EHC is good which it is most of the time. There is a thread on disconnecting, cleaning, and spreading Dielectric Grease on the pins when installing the two connectors for the EHC.
What I figured out on my bike is the ignition switch grounds the EHC to turn it on (Bob Lockwood explained this to me). Hence the electrical circuit is critical. I tested my ignition switch and it appeared to be good. There are two (I don't know why) connectors between the EHC and the ignition switch. One is under the coil cover and the other is under the gas tank on the backbone. I replaced the one under the coil cover with a deutsch switch and instead of daily shutdowns, I get about one a month. If the condition changes, I will solder the connection under the gas tank. But I feel extremely comfortable with the monthly hicups so I am leaving it alone and riding.
I don't even think about it when I ride. But when I get a shutdown, I reach down to cycle the ignition switch, hit run, and then start. It takes very little time and the last time it happened when riding with CurtK, I was out in front of him and he didn't even notice I had a shutdown.
It is also important to eliminate one item as the possible issue one at a time so you know you fixed it rather than going crazy and replacing everything and not solving the initial problem. Having said all this, I was lucky enough to get a WP via the very last group buy which is sitting on the shelf in standby in case I need to replace the EHC.
You just need to understand that an interruption of milliseconds via the ignition switch will cause this.
