One time when it had been sitting for several days without being driven it stalled several times even though the temperatures were in the 70's. Another time, most untypically, it just wouldn't start until I operated the priming pump a few times. Could these be signs of lift pump failure?
This does sound suspicious to me. Especialy the part about not running untill the primer was used. There is a newer design available for the priming pump, which is supposed to eliminate all leaks. Mine cost about $18. This type of priming pump has been mentioned on this board before, it does not need to be screwed out to pump.
I know a man here in Seattle who has had some starting troubles with motors like these (inline Bosch inj. pumps) includina a Datsun , that he swears he has fixed by replacing the priming pump. It didn't work for me though.
