stalled into a turn, slow speed
 

2002 ford escort just stalled while making a turn while trying to park. started immediately, no noises. I know that I will need soon to replace the power steering pump. when it is cold it likes to seize a little and makes a whine. so that's on the horizon, but is that a reason for it to stall out? the steering did feel like it seized when the car stalled. this is so far a singular incident, but would like to get the opinions of other escorters on this matter. glad for your help.

how many miles are on the car, when was the last tune up?

110+thousand, tune up within the last year. maybe about 8 months back. actually just finished redoing the engine cooling system. replaced everything but the fan and the gauge. valve grind, gaskets, checked the head for cracks, etc.
