Plants will generally blossom in fits and starts, not necessarily because of their type, per se, but more because the mechanisms that determine blossoming are reliant on quite a few factors. Think of things like temperature, watering schedule, soil fertility, potential pests, current fruit load, etc. Depending on how much these things vary, your blossoming and fruiting can vary as well.
That being said, I've not seen that my peppers are really any more variable or not than other plants like tomatoes or squash. The biggest factors for me have always been watering schedules and temperature. As more fruit is on, plants tend to want a bit more water and as temperatures go up the ground loses more moisture to evaporation. However, be careful about over watering. I tend to only fertilise at the start of a season and focus on keeping organic mulches going, so don't end up with much in that variable, other than possible tail off at the end of the season.
I would say you should almost definitely expect more blossoms this summer, unless your plants are highly stressed or you get a pest problem that basically kills the plants.
