Hello, I have a 1993 silverton running twin 503xl.carb engines starboard engine will run fine for 30-40 min then will start to loose rpm. I can back off the throttle and keep it running. when it first started happening it was once changed fuel filter it was fine This season new filters new rotor cap plugs problem is back runs fine 30 min then starts lose power Switched tanks problem does not move to other engine. Anyone else have a problem like this? I’m thinking the distributor, module was replaced no change
