Is your fuel tank vent clear? I had the very same experience and it was the bloody tip over valve gone wonky. Yours is not necessarily an electrical problem, more like 50-50. 5 Miles is typical of a vapor lock/fuel restriction as much as a overheated or shorted out relay. I have now owned 5 Speedys (not all at the same time) and two Americas and the very first thing I do upon ownership is omit that valve and reconnect the hoses with a 1/4" open brass tube.
