OK, I would change the the three driver transistors associated with the
left flipper on the Flipper control board. I can't tell with set of
drivers is associated with the left flipper as the circuits are noted as
coil A and B.
Coil A -- Q1 MPSA42, Q2 TIP32C and Q3 TIP36C (LED 1)
Coil B -- Q8 MPSA42, Q9 TIP32C and Q10 TIP36C (LED 2)
When you push the left flipper button note which LED lights and that
will be the Coil circuit to work on.
As for your other problems I would start at the power supply board.
Fuse clips are a problem there as well.

What are the chances anyone will still reply to this thread? I'm having the same issue. All 3 flippers died mid game but coils still have power and all fuses and clips are fine.
Check what is common to energizing the 3 flippers.
I'd start with the cabinet flipper button switches. Do they share a
common connection like a ground or common return line?
That would be a great place to start.
Work from there.
