Quick 200r4 tranny question

I am running a 200r4 in my roadster. I bought a wiring kit to lock up the converter and it worked good until last week.
Now when I come to a stop, the converter is still locked up and stalls the engine unless I bump it into neutral. When I take off from the stop, I simply bump it back into drive and it seems to be fine.
What gives?

I had a tranny do that also (FWD BeUCK)

Theres a solenoid that applies pressure to the converter, applies the lock up clutch. It was sticking, but evenually it would cool enough to let go.

Hopefully it's just your wiring.......
