warm running issues, cutting off

1991 900s non turbo
Last summer I was having issues with the car running at speed and seeming to suddenly lose either spark or fuel when at partial throttle. If I floored it, it ran great. But while maintaining hwy speed, it would occasionally cut out.
I changed plugs, wires, dist cap and rotor last fall and it ran great since then. Friday night the problem returned, with temps in the 60degree range, and disappeared on Saturday night with colder air temps. It was running fine except for after stop and go traffic. I assume it raised the underhood temps and whatever is cutting off fuel or spark stopped responding.
I do get occasional CEL's. But the codes are usually fuel/air mixture codes which don't tell me much that I don't know.
Could this be a crank sensor?
Thanks,
Kevin A
