Occasional Hesitation Getting Worse

The car is a 1991 900s. A while back it began hesitating under heavy load (pulling on to the highway), but the odd thing was it would to it very specifically at 2500rpm, and by 2600 it would be fine again. Also, it would stop completely when the car was warm.
I noticed that it only did it if the car hadn't been driven much, as in it had been left for 5 days. If the car was used as a daily driver the problem wouldn't present itself.
More recently though, the hesitation has been showing up across a more broad rpm range, although still only if the car has been sitting for a few days.
I know the basics like the fuel filter, and distributor cap.... but where else should I look? I'm quite confident in the fuel pump, so I don't think that is it.
Thanks!
