JA: Sometimes things that you think will be really complicated end up being easy to fix with a Mercury. The Mercury Mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: Then it dies
JA: Are you hoping to fix this yourself?
Customer: Yes
JA: Great! What have you tried so far?
Customer: Spark plugs and wires and springs
JA: Is there anything else important you think the Mercury Mechanic should know about your Mercury?
Customer: Replaced
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Mercury Mechanic about your situation and then connect you two.

Any ideas

Thank you. Without hearing it, it may have an internal engine problem. Piston or piston connecting rod. But before you do any repairs, have the PCM (Engine Computer) tested for trouble codes. It could have low fuel pressure which will cause what we call spark knock and also stalling.

P2195 - Lack of HO2S-11 Switch, Sensor Indicates Lean. It is possible that the fuel pump is not putting out enough fuel pressure.
