From my experience, you are always going to run into stressful situations - no matter how well managed and well documented something may be, there can be emergencies, crunch times, deadlines, etc.
That said, there are several factors here you need to consider:
How well managed are your projects?
A poorly managed project with few or no milestones can easily go sour fast. If this is the case, both your previous jobs may have been unnecessarily stressful, but another company with another approach may be a better fit.
Is this typical of the industries you are working?
Some jobs are easy - low pressure with low expectations because you aren't doing mission critical work. Others are in many ways have a lot riding on the quality of work you are producing, which can impact how much pressure is involved with the tasks.
Have you considered that you are the reason for the stress?
Being self critical and over analyzing problems leads to stress to the exceptionally detail oriented. Having a lack of passion (which you seem to indicate) can make complex tasks feel even more insurmountable. Your perceptions may be causing the problems at hand.
If you answer yes to 1 or 2, this is completely environmental and you can solve this problem yourself, you just need to very upfront with potential employers that you are interested in their working environment.
If the answer is 3, that is something that will follow you as long as you are unhappy or disinterested in your work.
