I've been having a similiar problem. Checks out fine at the indie but on occasion it seems to do the same thing as described. Matt and or Tsquared do you know which hose was collapsing?

Here is the follow up. It was definitely the compressor seizing up for the ECC. Expensive part. I have driven it in all types of heat for about 400 miles since I picked it up and it now works like a dream. I hope it isn't your compressor as well. You should be able to get your guy to figure it out by essentially connecting the compressor up directly, don't quote me on that because all the paperwork regarding this is about 250 miles away, but the dealer hooked up the compressor on its own (bridged the contacts, shorted it, something) and ran it and pinpointed that it was locking up. I think I saw how to do that on the ac thread here. Good Luck!
