I have a 2004 Dolphin MH with the Workhorse 8.1L Vortec engine and have had an on going problem with the engine losing power. It has happened on 3 different trips. At first I thought it was a fuel pump problem and had that replaced. (in the gas tank). It happened a 2nd time and the mechanic again worked on the fuel pump and it seemed OK. It just happened the 3rd time. The "service engine" light came on. (Codes: P0131 and P0151 - "low voltage Bank 1 and Bank 2) I was driving on the interstate at 65MPH with no sign of problems and the engine would just slow down to 5-10MPH. I would pull over then all of a sudden, back to full power. It appeared that when the engine cooled down a little the engine would start normal and run great but when it got warm, it would start dying out again. I did get home but this happened approximately 8 - 10 times on a 200 mile trip. The symptoms appear to be a lack of fuel problem but maybe more of a computer problem.
Has anyone out there had a similar experience? My instrument cluster also has stopped working but I'm estimating the mileage to be about 48,000 miles. Any help or suggestions would be greatly appreciated.
