Onan generator issue..
Ok guys, question on my generator. I have a 2012 Greyhawk 31DS that I purchased recently. We're totally in love with the unit!! However, I do have a small issue with the generator. The generator is a RV QG 4000. I can crank it up first thing and it will run fine. However, somewhere between 30 minutes and 3 hours usually, it will just surge a couple of times and die. It won't crank again for a while. When it does crank again, it can run for another 30 minutes or up to 3 hours. Really weird!! I have changed the oil and air filter. Considering also doing the fuel filter. Any other recommendations?? Thanks in advance for any help!!
