Shuts off after 15 mins - Patton PUH680-U Utility Heater

am not a tv technician but check the sleep mood a key on the remote may be stuck

Fuel pump going out. Once it gets warm after 15 mins the o rings loosen up and cause it to loose prime and shut off. After cooling for 15 mins they have shrunk enough to build pressure again.

Yes that is a shut off valve and im thinking either its a lose wire or it needs to be replace

Hey Jim why havent you replaced the Ign module?It sounds typical of it. Good job checking fuel pressure BTW most dont.

the wooshing maybe the oil/freon migrating thru out the internal system...
The cycle depends on 2 things... t'stat operation and timer. The timer usually shuts off freezer every 6 or 8 hrs for 20 to 30 mins. But the t'stat (once it reaches desired temp. should shut off freezer every 15- 20 mins. for an average 10 -15. So 15 mins off min 15 mins on (that is if the doors is not open) you get my point something like that...
but the way you describe to me it sounds like the t'stat. set it at 1 if it dont shut off and you are absoultely sure you got zero degrees (use a temp. reader) then replace the t'stat

hope this was helpful
let me know if this didnt work then plan B

suggest change crank sensor-rear of engine pas side

You battery will have to be replaced.

I had the same problem on my craftsman 18.5 hp, the problem was in the choke, the spring was broken, and the choke was not free, replaced the spring and it is fine now. Check it out. Good luck.

That sounds like your alternator might need to be replaced.
