It is implied that Jotaro's peak is when he was approximately 18 years of age. That doesn't necessarily mean Star Platinum was weaker after that point (obviously until Part 6 when he is 40), but instead that it's strength was at it's highest from that point onward. However, I'm quite skeptical about Star Platinum being outright weaker in Part 4 in terms of physical strength and durability. Though it's Time Stop has diminished to a mere two seconds in Part 4, I see no reason to believe that it's overall strength had as well. Are there any implications in Part 4 that Star Platinum had weakened since Part 3 other than it's reduced Time Stop duration?
