I suspect probably your problem, from the sounds of it, is that you are taking off without 'breaking the lip' - ie you stop paddling too early, or start too late. Either way you end up too close to the top of the wave when you are popping up (if you google 'breaking the lip' or similar you should be able to find videos showing as its kind of hard to describe). You will see surfersdont actually take off right at the top of the wave, but a few feet down the face.
Remember how water flows work in a wave. Wave energy is rotational, with the direction of the rotation going from the bottom of the wave to the top. So water is being sucked up from the bottom to the top (which is, in part, why waves curl when they break and, indeed, the rotational energy is why waves break).
If you are too close to the top of the wave, you get sucked up as well and spat over the back. After you have popped up, gravity should allow you to break that and head down the wave; but when you paddle you are only barely overcoming the force and during the short 'stop paddling/pop up' period, the water movement might be enough to send you upwards. Plus the lip of the wave doesnt have much power, so if you pop up too high you might just not have enough thrust behind you to push you down the wave. Finally, if you arent paddling fast enough, the wave just goes straight by you.
Steeper and esp steep and large waves are a real problem for this.
The only solution is to paddle faster and take an extra stroke after you think you have caught the wave and weight your board to go down the wave (not tilting back to stop it going down). The extra stroke and weighting can be scary, because you have already started down the face a little bit and your immediately response is to stop paddling and jump up. In small weak waves sometimes the weight of the surfer will break the lip, but in anything bigger or more powerful you need to position yourself down the face a little bit. Aiming across the wave slightly helps, because you arent heading straight down and panic-ing yourself, the angle is more subtle
This is a difficult thing to learn to do because it feels wrong and unsafe and you will sometimes get it wrong and disappear 'A over T'. But if you understand 'the physics', you can figure out what is happening a lot better. When it works, it feels so natural and unscarey that you wonder what your problem was - until the next wave doesnt work....
I'm not sure what you mean by saying you take off straight and bottom turn - if you are at the bottom of the wave, or nearly at the bottom, and you turn and end up going off the back of the wave, then you are just turning too sharply.
As you go across the wave, there is a need to aim slightly down the wave to overcome the water movement, but its not really a big thing - I guess dont aim straight across, aim down a little. You can always do a slight turn back up the wave if you get too low.
