Eclipse lost power when driving. Throttle wouldn't work. Car won't turn on now.

170,056 and its an automatic

Possible timing belt, grinding noise ? If I could hear the noise would probably know. (bearing or component locked up and belt squeak while turning against pulley). If timing belt is bad the valves will be bent, if happened at hwy speeds.

No the car was traveling like 15 mph and rising then it just lost power the throttle wouldn't work and all the fluids are at normal level and condition

I'll go with the timing belt theory........time for a visual inspection(tear-down) to verify what it IS NOT.

Yeah that's what I'm thinking too but would the timing cause like a knocking noise aswell

If the valves are bent YES. Every time a piston travels to the top it will hit the bent valve. The valve stays down in the cylinder and the pistons keeps hitting them. Sorry
