Was coming back for Santa Fe NM and stopped and  filled up with 130 gal of fuel and spent the night at Oasis RV in Amarillo. The next morning after entering on I40 east I noticed check engine light (Yellow) on the dash counsel come on for a few seconds and then go off, I also received a message on the Diesel Pro? come on and said FUEL CIRCUIT TEMP HIGH. This continued for around 10 miles and I called James Veal @ Tempest and discussed this problem with him. He said I may have a sensor acting up, would not damage the engine and would probably go out. So after 15 miles I went up to my normal 65 MPG and the check engine light did go out and did not come on again. All gages and performance was normal while the light was coming on. The fuel filter also looked fine 1/3 fuel in bowl.

Any inputs would be appreciated
