Read the blaster CFM requirements.

Try turning the pressure down to 90psi so that your 125psi tank pressure will last a couple seconds longer.
Next, get a bigger diameter and shorter air hose.
You can't flow much air through the 1/4" air line you are probably using.
By short burst, I mean less than a second. The psi on the gauge is still reading basically full. And as I said, I am using a 30 foot 3/8" hose. It would seem to me that the pressure regulator is the problem.
