Replaced upper intake plenum gasket and throttle body gasket, put it all together, ran fine until I drover about 80', died and wont start, still thinking has something to do with the temp. of the motor, problem....

Engine Coolant Temp sensor on this rig has a 15mm diameter thread vs. those offered as a replacement with an 8mm thread. Anyone see a reason for this?
