I put in some Tulipa clusiana and some daffodils maybe three or four years
ago. The second year after planting they came back in the spring with some
flowers, maybe 70%. This year I only go one daffodil bloom. Should I get
rid of all the bulbs and plant something else instead, or is there anything I
can do to get them to bloom again?

I looked up the cllimate of Houston on Wikipedia:

https://en.wikipedia.org/wiki/Climate_of_Houston/

Houston has a hot climate with more or less even rainfall throughout the year.
Tulips prefer (or may even demand) dry summers. In your climate, istm that they
would be prone to attack by fungal diseases.

A question: did your bulbs put up foliage this year, or was there simply
nothing where you had planted them?

There may also be issues relating to soil fertility and pH.
