Micrologix RTD 1762-IR4 Reads as 0 Ohms before correcting

I have a Micrologix 1400 with an 1762-IR4 RTD. I use it to read airbag resistance on seats on an assembly line. I am often getting into a situation where it is reading as a short circuit, when there is not a short. Then it kind of just goes away after minutes. I can't find a rhyme or reason to it. Any ideas would be appreciated. When in this state, any resistance applied across the RTD inputs doesn't read correctly.
