      Try the following:
      <br>
      <br>
      1. Turn the compressor off
      <br>
      2. Bleed off the pressure in the tank down to, say, 30-40psi
      <br>
      3. Turn the compressor on.
      <br>
      <br>
      What happens?  Does it start?
      <br>
      <br>
      Sounds like your unloader valve might be going bad though since
      you have a bonafide 5hp motor, I'm a little surprised it can't
      power through it.  What size circuit do you have it on?  30A?
