vapor lock is very highly unlikely. the pump is constantly pushing fuel thru the system and is always recirculating fuel thru the system back to the tank. so unless your pump is bleeding air into pressure line vapor lock is very unlikely. even if it was doing it it would cause some rough running momentaerily. it would not cause an instant shutdown. doing freeway speeds. you either have heat related or vibration related electronics failure. there is a control module inside the distributor that you can remove and have tested at some auto parts stores. if removed ensure you put plenty of silicone thermal grease between it and the base to ensure it draws heat away from module to prevent overheating and shutdown. if this ends up being your culprit accel #35370 makes a excellent performance replacement but is pricey at $85.
