In another post I said I got my AquaHot running but not completely. 
I replaced the pressure cap and checked the fuses and it lit right up. Afte a couple of hours though it wasn't running.  If I pulled and pushed the second from the left fuse up it was good for a few hours again.  On again, etc. 
The fuse is good, thoroughly checked.  Acts like a fuel issues??  Like it burns until the fuel reservoir is empty. Then kicks off and I can restart after it refills?  Some type of restricted flow?
Any ideas?
