I think the key is that the trouble occurs when the tank you are running from drops to a certain level. One though is that your lift pump isn't working on the engine. When the fuel level is high enough you have sufficient gravity feed to run the engine at load, but when the level gets too low the engine has no way to pull the fuel up.

One test would be to rig a temporary fuel line to a bucket and see if the engine runs under load that way, and if it works with the bucket held at different levels.
