Can a MATOC IDIQ be converted to a SATOC if one of two contractors has performed poorly? Can open years be exercised for only one contractor within a MATOC pool?
No it is not allowable to convert a multiple award into a single award task order contract. You may consider continuing on with the MATOC which is, if one of the two contractors doesn't participate, in effect a SATOC. Another less preferrable option might be to terminate the MATOC and solicit for a SATOC.
