I would check the band crystal for 40 m, and band specific tuned circuits.

Subject: [Drakelist] R-4 PROBLEM
Hello to all,
I am having a problem with a R-4 I just got in the shack, all works good,
receive is great, but on 40 meters only it seems. when I first turn radio on,
warms up 40 meters is great good signals maybe about 15-20 mins or so, the
receive just fades away. I thought might be band switch move that around, move
all controls does not come back. I switch to 20 meters all is good.
I have not checked any tubes, which is a next step and have not really dug into
it. I wanted to see if someone had this problem and can point me in the right
direction before I go further.
If I shut the radio down and next day turn it back on 40 is good again. I had
the cover off for a few days while I was cleaning and replacing the blue
filters
and it seems 40 held up. maybe a cap problem or heating?
Thanks to all
Phil KM4OP
