Fuel Injection issue

[buck]

After a long day of riding across Idaho, I stopped for fuel and when I turned on the ignition, the fuel injection system did not pressurize. Turned key off and then back on and got the familiar 'whirring' sound of the fuel pump. Called Carl's Kawa in Boise and they called the factory technician who couldn't explain the problem. Possibly a short or poor ground connection. (I had radiator and regulators replaced earlier in my trip due to metal debris, so electrical system was worked on, but no problems for days after). Kawa suggested it may have to fail completely to diagnose which is not acceptable. Spent several hours talking with dealers along my trip and no one had an explanation. So, if I turn ignition on/off/on it pressurizes and will start and runs normally without any issues. Will pull fuel tank and check all connections. Any thoughts? Buck
