pt cruiser engine stops at a stop sign

Does it die out as you slow down or after sitting a few seconds? A locked up torque converter will cause this on an automatic but need more details to really know.

no lights on the dash but check engine light is on

check engine light is on and car starts fine but fizzles out at stop light

Get the codes checked for free at your local parts store, it's probably not the TCC but that code will give you a start.

Hey try pulling the ASD relay in the relay box mine is a 2005 it's near the firewall under the wipers get one at Napa I was surprised too. Open your gas cap and close it then plug in the new ASD worked for me they are about $20. Hope it works!
