mechanic has replaced cap and rotor 3 times this year. He now wants to replace the distributor gear. Vehicle has 157000 miles on it and it runs fine other than this annoying problem. Is the tahoe susceptible to moisture problems? New fuel pump and filter

Engine6,
From your post I'd say this 'mechanic' is just throwing parts at it with no fix. The same parts THREE times in 1-1/2 months?
You DID say "this year".
Why would any mechanic (who knows what he's doing) replace a dist, cap and rotor three times in one year when the first ones didn't correct the issue?
I doubt ANY vehicle is 'susceptible' to moisture.
The next time you start it up and it runs fine, use a water spray bottle and lightly squirt (not spray) a little water at all electrical components one at a time.
This includes the plug wires. (You can use any plastic tissue (Eg, Stretch'n'Seal) to keep dry the wires you don't want wet)
Avoid drowning the component, take a clean dry cloth (or compressed air) to eliminate the moisture then move on to the next.
By wetting one at a time you have a better chance of locating which is the culprit.
When squirting around the alternator, be careful to NOT get water inside.
The fault MAY be an ignition one. Perhaps wires rubbing together somewhere causing an intermittent short. This would also allow a moisture penetration.
Maybe even a wire with a hardened insulation and a partially broken wire inside.
I'd advise you to find a reputable qualified tech/shop who can diagnose a problem and fix it without draining your bank account by throwing parts at it.
If you are able to locate a good independent that you are satisfied with, stick with them. Trust me on this, it's to your benefit.
Ask friends, relatives, co-workers and even shop customers if they are satisfied with their shop of choice.
I've been going to the same independent for all my vehicles (an '02 Tahoe, an Olds and a Toyota) for 19 years now.

NORMALLY the problem you have is repaired by replacing the wires....using the previous way to be sure will usually reveal the defective spark plug wire especially at night/dark...
make sure the replacement wires have the correct resistance...also plugs need be checked....don't want to put new wires on old plugs....
