1st thing sell me the car for 1 dollar.

Sounds like flooding.
Fuel pressure?
Float levels?

I'm thinking it floods and fouls plugs and never runs right afterwards.
Could be heat related effecting fuel too.
Hot fuel ...line too close to exhaust
Foam and bubbles will flood the carb too.
Needle and seat can't control foam.

I had a similar situation many years ago.
Fuel was too hot...flooded carbs at random times.
