I am experiencing a loss of power and engine overheating. The 3782 engine starts as normal but when driving has a lot less power and after use of about 10-15 minutes loss of power will be severe in all gears max speed maybe 20mph at a push. Engine will also be overheating and higher reading than normal 180 to 200 Fahrenheit. There is also a burning smell in the cab. Any help would be greatly appreciated. Thanks
Eeek, sounds like a possible head gasket failure. Check your coolant and oil. If the coolant is low top it off, and if the oil is milky, you are getting coolant in your oil which is usually a bad head gasket.

Fuel pump might be the problem. But it also might be a weak battery.

run it and let it get hot (not to the point of overheating just let it warm up to normal or slightly above normal). put your hand near the upper radiator hose, if you feel not heat, touch it, be careful as it may be hot. if it is not hot at all but the engine is warmed up it is the thermostat, the thermostat is located where the upper radiator hose connects to the motor, usually a 2bolt metal fitting, if this is the case just replace the thermostat.
