One more thing to check is propane pressure. You might also pull the propane line at the water heater turn propane on and listen at the line. If you hear gurgling you probably have  oil in the line back at the propane tank.

Barry you could have  a touchy switch on your kitchen cabinet if the contact is getting weak it could be playing with you also. Not necessarily the heater itself.

I'd forgotten: last year the hwh was 'cycling' on & off: sometimes it would work and then........a smart tech found the problem: a fuse/breaker. Replaced........hot water on demand!  ^.^d

add on: found the invoice, my tech called it a "Atwood Cut-off'.

Bypassing the fuse is an...

My hot water heater was doing strange and UN-predictable things due to a faulty switch.  I replaced that sw and all is fine so far.  Have a great day   ----  Fritz
