Just a slight chance but worth checking. The front temp sensor reports to the PCM and not the gauge. If that sensor is failing it will send erroneous signals. If you have a OBD scanner that will show you the temp as reported to the PCM and it is either excessively high or low, a replacement temp sensor could solve your running issue.

hope this helps
