383 dying issue

I have a 70 Roadrunner, 383 cammed, holley carb/intake, headers, MSD etc.
Car sat for around 2 years.
Replaced bad starter and bad starter relay recently.

Drove the car today, no issues then after around 30 minutes it died in 3rd gear.

Cranked it, it started and a mere 3 seconds later it died again. Had to repeat this process and drive home.

Not sure if its a carb issue(accelarator pump), if its hydrolocking. The clear fuel filter in the engine bay isnt full of gas when cranking. Any advice helps. Car did sit for quite some time so not sure how to diagnose. Thanks.
