I have a hard time believing I jumped timing since it did not instantly happen, but you think it is worthwhile to check it anyway?

I also have a hard time believing the timing chain jumped because you said it got worse with time. A jumped chain would be poor running IMMEDIATELY.
Suggest setting up a plug wire close to the plug with a little gap so you can see the spark jump. Then see if the color and/or intensity degrades with time after start up. You need to confirm its the electrical system, and not something else, like an extremly dirty fuel filter.
I once had a Maverick way back when that misfired after it was warm, only during acceleration. Found problem - it was the center contact on the rotor - it did not have enough pressure so I just bent it up and problem solved.
Check to make sure there is no corrosion on cap or rotor and that its DRY inside.
Good Luck and let us know you progress!
