The car is a 2004 Honda Civic Ex 1.7

The car keeps dying, no power, cuts out, won't go pass 3500 rpms, check engine and emission lights are on...

What I have done is replaced battery and alternator and throttle position sensor

Overnight I'll put a battery charger on car and let it charge all night. When I start it up no emission light is one and car runs perfect. Then when I hit the first Stoplight the car instantly dies and looses all power and won't go pass 3500 rpms.

I've heard a Crankshaft Position Sensor could be the issue... But would that cause the battery to loose juice?

P0336 BUT when I had Autozone run there computer I told them it was a DX instead of a Ex... Probably have them run test again later today when I get off work.

So fix the code.That doesn't matter.

But wouldn't a bad CKP essentially prevent the car from even starting? I know of people that had bad CKP and the car wouldn't even start.... In my case the car does start up.

What makes you think the P0336 code is about CKP?

Research it.
