So... i tried this and it didnt work... it still cut off, luckily i wasn't far from home and i was still able to make it back home. i parked it and let it run it cut off agian in about 10 minutes while it was sitting still. i started it back up and it ran and continued to run for about 25 minutes. i didn't try to drive it anymore i just let it sit there and run.... idk what to do im going to pull the bed and check the tank for sludge.. probably drain it and clean it out and see how that works... im out of ideas i have no idea what the problem is and i dont have the money to take it to a professional. so please guys any ideas will help..
