FlightRadar24: airplane shows on the map intermittently

[popPilot]

Has anyone experienced one specific aircraft showing intermittently on and off (like for 1 minute) on FlightRdar24?
I thought about the FR24 ADSB coverage for a minute, but this happened specifically while the aircraft was taxing at the airport and only to this aircraft I was tracking, then I thought could this be faulty transponder?

Aircraft type: 737-823
Airport: MIA

There are lots of variables with picking up ADSB on the ground. Who knows where their receiver is. If hangars, etc get in the way, the track will be choppy.

Also, for the cheaper SDR receivers, being TOO close will overload the receiver if the gain is not adjusted properly.

An airplane at MIA is missing in action?

If you have UAT such as tailBeacon or GDL88 or ... (about 20% have this for ADS-B Out), then the coverage of ADS-B receivers that feed the various tracking companies have large areas where they only receive 1090ES and don't receive UAT, so you fall into a coverage hole.
