Intermitent Coolant Leak

I have an 88 3/4 Ton Chevy travel van with a good old 350 V8 engine. I can drive the old girl for hundreds of miles with no problem but every now and then I get coolant leak. Drove the vehicle on a 500 mile trip earlier this summer with no problem but today I drove it 20 miles in cool weather and it leaked again (probably a cup or two) I've tried to find the leak source but with the cabover design of the van its very difficult to see hoses pump etc..

I'm thinking that its not a hose or the pump or the leak would be consistent rather than intermitent. Any suggestions on what would cause an intermitent leak like this and where I should be looking for it? Its never overheated even in very hot highway driving. Any ideas before I start taking things apart would be very much appreciated Thanks a lot.
