While troubleshooting some starting issues decided to check on the bean can and found the electrical plug brittle, with debris lying beneath the bean can. So much that I am afraid to touch it for fear of having to replace the entire unit as I cannot find a replacement pigtail via the microfiche. I thought maybe removing and dipping the connector in a plastic coating or epoxy. Any ideas?

I recall a member or two mentioning a source for the connector parts. Hopefully, they will chime in.

I hope nothing as drastic as this

missed photo $330!!

The connectors are known as either JPT or "Junior Power Timer" connectors.
The world has largely passed them by but they are still available from places such as RS Components. I did a quick search on eBay and there is at least one seller with 3-way JPT connectors at almost reasonable prices.
I spent a long, long time hunting these connectors down, were I in your shoes I would not bother. the only things that JPT brings to the table is that the connector is moderately waterproof and has a locking bail to prevent the thing from coming apart from vibration.
I would go to your nearest auto electrician and but two each of three way waterproof automotive connectors and switch over to them.
Actually, me being me I wouldn't do that, I would simply strip the existing plug and socket out and solder the wires together on the theory that in the once every 10 years or so that I am likely to need to break the connection I will still have a sharp pair of side cutters and a working soldering iron. "Boss" Kettering (yes the bugger who more or less inventing the Kettering ignition) once said "Parts left out cost nothing and create no maintenance issues".
If you really want to maintain a "plug and play" environment and do not want to pay the cost of waterproof automotive connectors - molex plug and socket such as used to power hard-drives, CD-Roms etc in computers would be more than adequate, buy two sets. You could even use good old house electrician termination strip.
Why buy two sets I hear you ask? Because with a 9volt battery and an LED you can make a device for setting initial timing via the "quick and dirty" approach, also you will then own a beancan tester that can tell you if the evil day to replace a 2AV54 hall effect transistor has arrived or not.

I don't have this problem with points in a can but if I did that is exactly what I would do. Any 3 pin connector would be fine and it would fix the problem for good.

Well one more time, thanks for the solution, I'll probably go the low tech route and use regular waterproof connectors.

Those wires from the bean can are 22-gauge. Quite small. Be sure to get the correct size connectors. You may need to visit an electronics supply store. I found some at Radio Shack but many of their stores are either closing or phasing out the small parts bins that I frequently haunted.
