Sounds more like the TCC (torque convertor clutch) solenoid is sticking.
This locks up the convertor at a designated speed and rpm. It should unlock when brake pedal is depressed, if it does not, it will cause the engine to stall.
There should be a small square connector on trans (usually blue, white or pink) this is TCC connector. Unplug it, if symptoms go away, then TCC solenoid is cause.
Drain and flush cooling system, this should be done at least every 2 years.
