I have a om617 that’s giving me hell if anyone can help me I was driving a week or so ago goin up a hill and my car just kinda puttered down and died on the side of the road I rolled to a flat spot got out not knowin what the hell happened did my bleeder started it up kinda took it a second to build back up went on my way then it does it again 20 or so min i had just filled up a couple days before figured nasty fuel or change my fuel filters so here’s where we are so far I’ve changed both filters pulled the tank out cleaned it and strainer blew both lines made put a electronic fuel pump on it and now every time it gets to operating temp it will putter down dies and I sometimes can get it started back up but usually have to wait till it’s cool I’ve read plenty of the fourms on ideas and what could be the logical one is that my heater grid when the cars plugged in makes a awful sound.. I’ve tried and thought of everything I can try help would be very gratefull!
