Everything you noticed. Time of day, hot or cold engine, wet or dry weather, rough road or smooth, what else was switched on, and whether anything was installed recently. A short phone video of the dash while it misbehaves is worth more than any description you can give at the counter.
Often, yes, and that is the right answer rather than a stalling one. A fault that turns up once a week cannot be caught in a one-hour slot. Ask how they plan to reproduce it and whether they will call you before the diagnostic time runs past what you agreed.
Repair, usually. A proper repair means the damaged section cut out, new wire soldered or crimped with the right terminal, and the joint sealed against water. What you do not want is a twist of tape or a splice connector jabbed through the insulation, because that is next year's fault. Whole harnesses are replaced only after fire or heavy damage.
