I experienced the same problem with my 7.5 QD. Crank, run for about 5 minutes and then shut down.  I have the 02 Monaco with the front door which I had to remove and used a floor jack to ease the Ginny out. I had to remove the top and side panels to get to the sensor, so I replaced the fan belt, water pump and sensor at the same time hoping for a maintenance preventive. it's not a bad job, but takes a little time. Good luck with yours. David

Thanks.   mine runs fine the first time i run it..  but if i shut it off, and restart, it will only run for 5 minutes.  Ill get to it next week.  :)

the last 3 mornings it starts and runs for hours..  if i shut it off,   it will not run for more than 5 minutes.   2004 coachmen elite 402ts diesel pusher.    looks like i can lower the unit down and crawl in to replace the sensor.   was just trying to learn a little.   fresh oil and filter change.    ive changed the coolant several times.    it will not fail in the morning which seems odd.

onan 7500 genset.   randomly getting code 24 after 5 minutes of run time.  it shuts off.   get this... only when its warm outside.   if i start it in the morning, its fine and runs for hours.   currently 67 degrees and raining.    same yesterday morning.    if i try to start it later in the day when its 80 plus degrees outside.   it will only run for 5 minutes, and quit.    not looking forward to changing it out, as its in the front of my class A, pusher, and it must come out the bottom.
