Though there are a number of other things known to cause this type of
problem, you might want to *re-check* those ground connections.  I had
precisely this problem with my '91 Westy and it wasn't until the dealer
actually disconnected, cleaned and reconnected *all* of the ground straps
(there are several) that the problem was fixed.  Apparently the on-board
electronics are extremely sensitive to the ground potentials or ground
loop currents that can develop from even minute ground path resistances.
Simple visual inspections, or even re-tightening, of the ground
connections may not be enough.
