Fortunately, my red seedless is doing fine. It's young at about 8 years old but I prune severely every March. The poor thing looks scalped when I'm done but each year it gives me more and larger fruit.
I have one problem, the grape plume moth larva. An adult lays one egg in each new spring shoot. The larva eats the newest growth, often the grape 'flowers'. I have not found a pesticide to deal with it so I carefully examine every shoot for curling indicating the larva. Hand picking works fine if done often in May. The vine is small after pruning so it's not as daunting as it sounds. I don't know what I'll do when it's 30 years old but I'll likely not be around anyway, lol.
Your vine may be old and in need of a hard pruning. Is it getting shaded out?
This is the nasty grape plume moth larva, about 3/8 inch long.
