Are your balls dull or old?
"Old" these days could mean as little as 50 games on them. Today's resins absorb oil at an astounding rate and need treatment to retain their performance. That includes even polished balls.
Most balls lose their performance, hooking and hitting power, gradually over time. You often don't see it until you stop carrying strikes you used to carry. What you describe seems very like this, unless you've bought some new balls in the past 6 months.
They may need a rejuvenation of some sort: oil extraction, resurfacing or both.
Also have you changed drillers? That could also have a big effect on your game.
Possible other related factors: new lane surfaces, new bowling center, new oil machine, new oil man, sudden weight loss Or gain.
