Sidewinder SD 85 alarm. What causes this alarm and how do I fix it? During this alarm it would continue to run fine but would not stay running during a cold start.

Hopefully it's a faulty oil pressure sensor however my buddy had this same SD85 code after a very cold morning start up. After verifying with a manual gauge 0 oil psi it ended up being the oil pump drive gear spinning on pump shaft. The bad news is it's a PITA to fix, the good news is it's a rare problem but I did see it happen. Replaced oil pump and drive gear and problem solved.
