Engine stalling after idling

[BUA]

twin 1980 305 mercruiser inboards.
Port engine problems.
After idling for 50 mins the engine stalls out. Interesting that it takes 50 mins for this to happen (has happened many times now).
No issues with the starboard engine ever.
Water temp, oil temp and voltage all fine when the stall happens.
Could this have something to do with neutral saftey switch?
Thanks for thoughts.

Thanks for the quick response. I've just put in 140 gals of fresh fuel. I've rebuilt the carb. I've had water in mixed with the oil in this engine due to leak in gasket, totally clean now. Starter issues, had to replace starter, teeth chewed to bits. Seems like something must be heating up that causes engine to stall after 50 mins.
