Got my truck in trouble -packed eng compart. full of snow. Now cleaned out and with no load, runs fine until eng warms up, then stalls, turn ignition off, then restarts and runs fine again, but then continues to shut down every mile. Something got damaged, but can't find what it is. It was suggested that the computer is shutting you down because it Can't read the eng or coolant temp. The engine is an M11 in a 1995 Int..I have no special tools but hate to go to a shop. Any suggestions??
