Hi All...Here is a new one for me.  My 87 Westy is running great, smooth, even idle, normal power.  I am cruising along at highway speeds (65-70) and I notice on a hill or trying to pass that there has been a loss of power.  It is pulling fine on level ground, but any additional stress (hill, head wind, etc.) and it can't keep up.  I pull over and notice a rough idle.  I stop the engine and restart immediately and all is well again, full power!  I went through this 3 times last night on the 3 hour trip home from Maryland.  Any suggestions.  Could it be a ground problem?

Thanks,
Finn Runyon
