At idle the IPR should not exceed 30%, yours is showing 85% which is either stuck at full close or being commanded to full close because of a HPO leak.
Your ICP is 596 and is normal at idle, but if you have a HPO leak, the IPR is closing to 85% to keep the ICP pressure up.
Do a air leak test to check for HPO leak. Sounds like you have the "no start when hot" symptoms.
