I have a 1995 gmc pick up sierra I replaced the fuel pump and fuel filter the truck will start and run for a few hours or days and then suddenly shut off and won't start again. sometimes it would kick in and start but now it won't start at all. Can anyone please help me I am desperate have been stuck on the highway had to have a tow truck pick me up, have gotten stuck 35 miles from home then it started about an hour later
