I have a 2005 250 FITCH direct injection. After about 30 minutes of running she will shut down, restart after a few minutes but can't get more than 2500 rmp. Diagnostic tests shows TPS sensor is cooked. They replace the sensor and the same thing happens again. Mechanics seem baffled and think the EMM needs to be replaced. The EMM was removed over the winter and sent out but came back there were no issues. Thinking maybe it may get overheated and shorting out the TPI sensor. Has anyone seen anything like this, I'm getting desperate and broke. Thanks
