95 gmc sierra ext cab 5.7 after several miles (10 or more) the rpms jump it acts like tranny is disengaging (jerks) and dies. Takes a bit to start. When cold or sat a bit starts fine
The truck will go long distance going 35
miles an hour.
I have replaced exhaust from headers back,
new o2 censor, fuel filter, fuel pump, cap,
rotor, plugs, wires, water pump, fan clutch,
temp censor (it was over heating),
thermostat, fuel pump relay.
What the heck is my trucks issue??
