I can't think of any failure mode in an OD that would only occur when 
accelerating.? The pump and accumulator need to maintain a minimum 
pressure of 350psi or so, so you'd expect a weak pump or leaky 
accumulator to cause disengagement, or slow engagement, when slow or 
decelerating.?? Throttle switch, relay and solenoid would most likely 
fail randomly.? I'd replace one at at time--starting with the 
switch--since it's the cheapest/easiest to replace--then go from there.? 
I've had both a bad switch and relay cause random disengagement.? If 
it's not the switch, the relay can be carefully opened-up and the points 
filed, to prove it's the problem or not before replacing.
