A month ago my fuel sending unit went, and I ran out of gas. I filled it up and treated with ethanol Sta Bil and it seemed fine.

Recently I noticed a miss at idle while leaving the marina. I changed filters, sprayed some cleaner in the carbs, got fresh gas. It would run for about 5 minutes then stall. The primer bulb would be empty. After pumping the ball til hard, it would start right up and stall 5 minutes later. I got it out of the marina and at WOT it wasn't full power. I can idle for a few minutes but have to pump it up and start again.

Just switched out the VRO unit for a brand new one. Same problem. I'll change fuel line and bulb, and plugs on Monday. It's been smoking alot. Gray smoke.

Any ideas?

Sounds like a bad air leak or fuel ines.
