About 3 weeks ago my 95 psd died on the way home at 98000 miles. Truck would just keep cranking. I installed a cps. Truck started up and was running. Now about 3 weeks later pulling about 8000lbs it dies again. Exact same symptoms. Went and got another cps. Started up and drove home. The very next day it did it again. Truck was running fine, started to studder and lost all power and will not start. Very same symptoms. Both CPS were from an International dealer.
I looked at the sensor and it did not appear to be damaged from something hitting it in the motor. What is happening to cause this??

Pleease help!!!!!!!
