While descending into ZZZ on the STAR; at around 28;000 feet; E1 fuel tank indicated Zero Quantity on EICAS and MFD. Also received fuel imbalance caution message due to zero fuel indicated in tank 1 and 1800 pounds in tank 2. We [advised] ATC and went into ZZZ1.  While being vectored onto ILS into ZZZ1; Fuel Tank 2 Quantity went to Zero as well; now indicating we had zero fuel on the airplane. Both fuel Quantities returned about 1 minute after this happened indicating expected fuel Quantity of 3600 pounds.Cause: Improper Fuel quantity indicationSuggestions: Have flight attendant do a visual inspection of top of wings to see if fuel was leaking out fuel cap?
