This just started to occur. there are 77,000 miles on the vehicle. It only happens after heavy rain while the vehicle is parked. When I start to drive the "event" occurs and goes away after driving several miles.

Do not ignore a flashing check engine light. It is usually an indication of engine misfire, and excessive fuel getting into the catalytic converter as a result. This could damage the cat at some point pretty quickly if left unchecked.

You likely have leaking coil boots - leaking spark. Plugs and boots will likely fix your problem. A coil could be faulty too - and testing will determine what codes are in the processor that will lead to looking at which cylinder is in question specifically.
Thank you, I'll be checking to see how accessible these parts are to determine if I can replace them myself. It is time for them to be replaced anyway. Thanks again.
