My 1994 f150 with a 5.0 was making a weird noise towards the middle of the truck on the drivers side a couple of days ago and then today I was hauling brush going about 5-10 mph and it would randomly die. It would start back up and run for about 10 more minutes and die, finally the last time it died it had a little of trouble starting but it did start. Could anyone please tell me the possible problems it could be

 

Most of the time when it would die would be when I let off the gas gas and press the brake to slow down, and the funny noise might not have anything to do with it
