Default Engine stalling problem

Well tomorrow I should know if my engine stalling, backfiring problem has been resolved. with the latest replacements of Distributor Cap & Rotor.
(Hope marine techs thought to replace 'Pickup Wheel' in the Distributor?).
All to be installed tomorrow, then a in-water test with marine techs. At least that's the plan....

If this does not correct the stalling and backfiring, then I guess I have to look deeper to the root cause???

Again, the engine runs smoothly for about 10 minutes. After the engine stalls and backfires, I can almost always start up right away, and run at wake speed, but that's all..... As soon as I begin to increase throttle, stalls again.

After talking to a multitude of people about my engine problem, both here in this Forum and others friends, the following suggestions have been given as the possible issue. Came up with a list of 12 possible problems,
not necessarily in any particular order.

Gentlemen... Place your bets on your number !

1. Ignition module
2. Ignition wires - broken inside insulation and shorting out
3. Coil bad
4. Ignition Timing not set properly - Late timing
5. Electric fuel pump-faulty pressure loss
6. Water in fuel causing lean fuel condition
7. Carb Accelerator pump sticking
8, Choke open or sticking
9. Anti-syphon valve clogged
10. Firing order - Plugs not connected correctly to Distributor
11. Carb jets clogged
12. Bad Valve
