That would be for a charged system, without the compressor running.
I just checked my quickie chart and r-134 would be 165psi at 118F without the compressor, so that's totally believable.
Go get yourself a cheap set of gauges.
I paid $40 for my first set and they lasted 6 years.(Other than the plastic knobs cracked and had to be replaced.)
right now, we dont know why the compressor is shutting off. Knowing high side readings would help narrow that down.
The high side could be getting too high and a pressure switch is tripped,
the evaporator is freezing up
