Replaced fuel pump and she fired up and ran great for 2 days, washed it and 2 hours later I was going to check on cows , she fired up and ran good again for about 300 yards. Then it acted like it starved for gas, I pull choke and it got me off the rode. Pulled it home and check for pumping gas, was not pumping any, pump not running when trying to start. I check voltage and got crazy readings from 5.2 volts to 6.9 volts. Maybe pump relay or igniter?? Also I pull pump to see if I hook to my 12volt jumper to see if it would run, it didn’t, I’m at a loss here now. Ideas please.Thanks
