Have the alterntor and voltage regulator checked.
It would if the battery voltage was lowered enough to cause it not to fire.
A control transformer marked 240V - 24Vac would have a control voltage of 24 volts.
I think the cause of ripple voltage would be from a bad ground or capacitve voltage.
fuse maybe or maybe multiple fuses by a voltage spike
Anything that would allow the high-voltage to jump to the wrong place would certainly cause the engine to run poorly. Buildup around the outside of the cap would hold moisture which would allow the voltage to arc.
I would suspect over voltage as to the reasons why fuel injectors would burn out. The pulse that opens the injectors comes from the engine control module so I would check that along with associated wiring. Check the wiring for shorts to other wires.
The thermostat control engine temperature. If it fails the engine can run hot or cold - that would happen long before over-heating caused the engine to stall.
Not sufficient voltage. Eat a donut or try pickle juice it's highly conductive.
Defective voltage regulator.
Bad voltage regulator
Could be EGR Valve.
If you mean prematurely burn out, there are several things. A faulty control module or even a bad plug or wire will cause the coil to produce maximum voltage or produce voltage too often. A coil is exactly that. A winding or coil of wire energized producing voltage which is then stepped up to a higher voltage winding with a step up transformer. The more often you send current through a winding, which will cause heat, the sooner it will eventually burn out.
