have transmission checked

First thing to check is your oil level. If low it will shut down. Check your alternator if it goes out then it will drain battery then shut down. Need more info. Need to know gauges when it shut down. Hope this helps

Have the cat converter check for failure and blocking the exhaust pipe. No codes will show . Test by hitting the cat converter with the heel of your hand and if it rattles get a new one.

NO

This is normal down shift, if it is slight. If it is harsh then it could be a software problem or a seal problem. ie.. sticking solenoid piston. You can get some transmission additive that helps with the seals. But again if it is slight and not throwing you threw the windshield I wouldn't worry about it.

think ur fuel pump or pump regulator which is in engine area is failin

It is an electric assist steering. On very heavy use the motor can become overheated and goes into "safe mode" only partial assist until it cools down. Repeated attempts at parrallel parking have been know to cause this.

Try checking the fuel filter or the fuel pump. Sometimes if you run the fuel until it is almost empty, it pulls debri off the bottom of the fuel tank and it gets stuck in the fuel filter. It them starves your engine for fuel. Sometimes if you bang on the fuel pump, it will loosen some of this debri, and the vehicle may start, or you may just need to replace the whole fuel pump.
