Mercruiser 140. Recurring issue. Dwell and timing set. Run a couple of hours and it dies. Below 3200 rpm seems ok. Above and she dies. Fuel ok. Vent ok. Filters ok. Jets squirt fine.
Hook up the meter. No spark. No dwell. Pull cap, put cap HV lead from coil to a decent gap from ground. Operate points manually. Weak, thin orange spark. Put it all back together. Have a snack. Five minutes later she starts and runs at 3k a couple more hours.
Coil?
