10 mins sounds like a long time. Can you confirm that a functioning system will not run a stove for 10 minutes?
11-14WC is about 0.5psi in the line. It should run some with the tank off, but 10 mins sounds like more than enough time to drain out the lines. Also a variable is how many feet of propane plumbing there is to pull from.
When you open the propane compartment it should smell if a leak is there. If on a trailer outside, then it will be hard to detect a smell if leaking.
Without the stove test, I would consider a leak in the line somewhere also, the gen would have the same effect.
Hopefully it is your tank or the hose/fitting that it connects to, or the regulator as these are easy to replace.
**wont matter how close the appliance is to the tank, just how much plumbing there is in the system. If you have 100 feet of pipe past the stove, then there is 100 feet of propane that can feed the stove…
