Is there anything hot next to the fuel line? I saw some people mentioning gas being heated to the point it causes "vapor lock".. GL

Are you getting spark at the plugs?
If not then I would be checking the emc. Let me know.
If so if you pour a little fuel into the carb when it stops running will it start and run for
a few seconds?
If it will then you know you have a carb/fuel problem.
