Dryer not heating, Interimittent Problem

Having an intermittent problem. The dryer turns on, drum spins, but you have no heat, checked the following components:

Heating Element (bad and replaced)
Thermal Cut-Out
Hi-Limit Thermostat

Checked the bad blower fan assembly inside the dryer, everything fine.

Checked dryer for proper air flow in order to dry properly. The ducting has been checked and is not clogged. Removed the dryer hose from the back of the dryer and inspected it thoroughly from where it leaves the dryer to where it exits home, clear with no kinks or clogs.

If you take everything apart, check the ohms, reset the fuses, spin the timers/switches and put back together it works for a few cycles and then goes back to not heating again.

Would appreciate any help or ideas.

That sounds like a loose connection in the wire harness. Which requires checking every connection and wire.
