Vermeer 504F - Hydraulic Issues

Had some trouble earlier in the season with some feeding issues on the pick up head, thanks to some good advice from forum members I have got those resolved and the baler has been running well...

UNTILL.....

I was baling straw earlier this week and now the tailgate wont stay latched. I draw the gate up tight and the indicator comes up, then a few moments later it starts coming back down. The gate cylinders are pushing back out and the pressure gauge on the baler shows goes to 100 then bleeds back down to nothing. The only thing I have done differently was I had to give the gate lockout a few twists because it was too tight to push right in when I stopped to clean some straw off the twine arm and the top side of the belts on the gate. I have tried switching the hoses in the couplers with the same result. I have a slight weep at the gauge but I cant believe that would be causing this (i will still fix it). I also have a hard time believing it is the couplers on tractor because it has been fine till now. I ended up hitting the gate lock after closing the baler to finish up, but that is not exactly a long term solution (other than to lose a few pounds).
I don't think springs are the answer for the gate latch because the cylinder will overcome them. What is there in the hydraulics on this baler that would be letting fluid back through to push the cylinders back out?
Any help or knowledge on the subject would be greatly appreciated...
