Default 120 psi b4 start up then instantly 60 psi even

Hi
Jason from New Zealand here, I have a very big problem I am hoping you guys might have come across before or might have an idea.
I have recently bought a s5 13b pp the guy I bought it off had fully rebuilt it ALL new seals and bearings. Housings appear mint no chrome peel, cracks ect plates are within spec.
Engine done 100 odd kms, to cut a long story short I got it compression tested it, reading 55 psi even on both rotors, so I rebuilt engine myself with new apex seals and springs.
Compression tested before start up reading 120 psi even both rotors. Then I started it, it started straight away ran for a minute turned it off then wouldn't start. I compression tested again and it's back to having no compression at 55 psi on both rotors???? Any help would be very much appreciated.

Regards Jason Mcguire
