Sounds like several possibilities.

But if your fuel pressure regulator is leaking, then it's a fire hazard and should be replaced immediately for safety reasons.

Once you've replaced it, you'll learn if the hesitation was in any way related to the failing fpr.

Leaking hoses and a problematic engine temp sensor or connections are also excellent candidates for evaluation. Keep in mind that you should examine the (two-wire) sensor under intake header #3. (The temperature sensor under header #2 is for the temp gauge.)
