ok Dave - when you say stop - you mean stop pedaling? or stop the flywheel?
i had to get off the bike for a few seconds to chase the cat while it was calling for 250W - when i got back on, it was close
to locked up - had to stand on it to get it going.
this almost makes sense - consider some weird granny gear say 24/50 - to create 250W with that type of mechanical advantage
at a low RPM it would have to be a huge resistance - the trainer sees low cadence, low speed, and would turn up the resistance.
make sense?
at a higher RPM, higher speed, the resistance would be less. this is because watts is an instantaneous measurement.
not sure if there is a setting to avoid this. thinking of it the opposite way, if you put in 250W and it didn't create any resistance,
the cadence would have to go up to take up the extra power.

I just re read Dave's post and I think you're right.
This is normal. Just lower the resistance while still pedaling.
