It sounds like bacterial wilt, where the entire plant is affected. You can diagnose this by cutting one of the stems and looking at a cross section of the vine. If it is bacterial wilt, you'll see thread-like strands of bacterial ooze. Touch the two cut ends of the vine together and then pull them apart. If you see strands, it's bacterial wilt. You'll want to remove the entire plant from the garden and remember to plant something other than squash in that garden spot. If you do not see the ooz, it's a different fungal disease. Could be powdery mildew. Whichever disease it is, I don't think you can save your pumpkin plant. It's early enough in the season to plant healthy new plants in another part of your garden. If you plant right away, you'll still have time for a harvest.
