Had a friend where the bearings stuck to the crank from sitting for a long time like that. Basically had the same things happen that are happening to your motor.

what oil filter you running..??? If it's a FRAM, good have collapsed.. You would think if the bearings stuck to the crank there is a bearing clearance issue then.. Might want to check the oil psi gauge.
also could put an oil pump primer in the motor and see what you get first before pulling it apart..;)

I would try a different gauge - you never know, sometimes they go bad too...

Like fast406malibu said above check the oil filter. I had a brand new Wix filter collapse on me after 1 pass.Also make sure no debris is in the line itself or at the guage. Good luck! Keep us posted.

Recently had a friend call me to pick my brain and had the same symptoms..... Turned out to be two bad cheap oil filters in a row that had collapsed internally and did the same thing. I second the suggestion of running a Wix filter, and we will only run the Wix Racing filters since they will withstand higher oil pressure operation. You also did not say what kind of motor, but if it is a Mopar BB with external feed lines they can suck air and still not have a visible leak, causing low or no oil pressure. Last things that come to mind are a loose or broken oil pump pick up, and then maybe the possibility of a stuck oil pressure relief valve in the oil pump.... ran into that one on a Toyota once resulting in 5 psi. It's not your bearings..... well, not yet. hehe Good luck and let us know what it turns out to be?
