QThread not starting on second call

Hello, I am having a trouble getting a thread to continue restarting until a listWidget is finished with all of the items in it.

mainwindow.h

Code:

namespace Ui {
class MainWindow;
}
class MainWindow : public QMainWindow
{
    Q_OBJECT
 
public:
    explicit MainWindow(QWidget *parent = 0);
    ~MainWindow();
    HeatTransferMain *hMain;
    QThread T;
 
signals:
    SimData(QString, QString, QString)
}

mainwindow.cpp

Code:

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
 
ui->setupUi(this);
hMain = new HeatTransferMain;
 
QThread * T = new QThread;
 
connect(this,SIGNAL(SimData(QString, QString, QString)),hMain,SLOT(SimulationData(QString, QString,QString))); // Connection of Main Data Structure
}
 
void MainWindow::on_StartSimulation_Clicked()
{
 
    RunMain();
}
 
void MainWindow::Progress()
{
        if(ui->listWidget->count()>0)
             delete ui->listWidget->takeItem(0);
 
        RunMain();
}
 
void MainWindow::RunMain()
{
    if(ui->listWidget->count()==0)
        return;
 
QString sim_name_it = ui->listWidget->item(0)->text();
 
emit(SimData(sim_name_it, Direc, Path));
 
    hMain->DoSetup(T);
    hMain->moveToThread(&T);
 
    T.start();
}

When the Thread is done for the first Sim_name_it, the progress function is emitted by the thread. The Progress function calls RunMain(), but the thread never starts. Any ideas will be helpful!

note: the code was edited for readability, if something is not defined it was probably removed because it was deemed not important.
