i have a 2003 sedan g35

So this morning i drive to work 20 minutes away

i get this burnt plastic smell in my car as im driving.

I get to work i open the hood
no smoke everything looks fine ..

I disreguard it . thinking it might have just been a plastic bag that got caught on the exhaust or something..

Today for lunch i go to the bank and pick up lunch
i still get that smell . Get out i cant tell where its coming from ..

Driving for 20 minutes then bam ..

Waiting at a red light .my car goes into limp mode . It barely wants to go but slowly im able to get into a parking lot .and park it ..

I parked the car . Because i have to go open the store so im here now .
Any ideas . ???

EDIT: ALL THE LIGHT ON THE DASH LIT UP . THE SLIP AND ALL THE REST ..
Other than yeah im screwed..
