It appears your problem is growing worse over time, this
may be an indication of the distributor Hall-effect sensor being
right at the edge of the timing window where the ECU must
also see the pulse from the flywheel sensor.

Besides timing belt stretch, another source of SLOW creep
of timing error is wear in the nylon gear where the 
distributor shaft gets driven off the secondary cam.

Come to think of it, there is probably a few degrees
between the primary and secondary camshafts 
accumulating slowly as the timing chain grows old.
