Been through a similar problem recently which now looks like is eliminated.
In the end I had high resistance through the ignition switch, marginal voltage at the battery due to loom losses and reg / rec getting a bit tired and resistance on one plug cap. The problem was finally eliminated after replacing one of the coils (including leads / caps) even though the old coil checked out fine from a resistance standpoint.
These bikes are getting older and electrical gremlins more common. Good luck.
