1978 Spitfire shuts off while driving.
Still having issues with my 1978 Spitfire. It shuts off randomly and then will only restart after a while of sitting. It has happened in very hot weather so I assumed it could be vapor lock. I wrapped the fuel line in heat resistant wrap but yesterday it occurred again. Minimal driving, maybe 3 miles max then it shuts down. I took photos and videos of the fuel line, fuel filter and ignition. I have used premium gasoline and it still happens. Is it electrical? Any help would be appreciated. I do not have mechanical experience so would need to take it to a professional. It was suggested that I could use a ignition spray to rule out vapor lock but by the time I towed the car hoe it started up again.
