hawk thunder startup problems

The other day my new Hawk Thunder was having this problem where it would try to start and then just get stuck. I realize the Hawk Thunder has this problem when using a normal power supply, but I am using the Hawk PS-2 power supply, so it should not be the case.

Oddly enough, the problem eventually went away after several attempts, and I have not seen the problem since.

Any idea what could have caused this? Has anyone else encountered this problem, and if so, what did you do to solve it? It made me look pretty stupid in front of my client... "ok, here we go ... errr wait a second..."

I didn't but the guy I work with did he had to let run like break in
