There is one other possibility.  Not as likely, but still a contender, and that's the pressure switch going bad.  The one on my 87 went bad a few months ago and it acted quite similar to yours.

I guess I have to swap and try another one, I just struggle with grok-ing  a switch failure mode
that causes THAT phenomena. Self heating? (a stretch ) Dunno.

As TurboDave said check the pressure switch. Seen many cause short cycle..

I had a painful email discussion with Rockauto last week.
Even though they will happily bill me in Canadian Dollars they will not allow me to send a PM
to one of the two Canadian Cardone depots (one a block from work) for a R&R - but I would have to send it to Philly for rebuilding.  :x

But Yes- I'll try a switch first.
Do you think anyone had a 1 1/2 socket in stock, nah.
After my Crescent wrench slipped and f'd my spare reservoir I realized:
A water heater element wrench is 1 1/2. and cheap.
And the guy with the switches was too busy with his Turbo garden party planning
to ship it.

The switch made no difference, the cycle rate stays the same.
I did score a PM rebuild kit, I don't know anywhere local I'd entrust with this valuable commodity.

The prattling purveyor of Powermasters from Pennsylvania has pronounced a paucity presently.
