Start up problems Jotul 350 Lil Diamond Gas Insert

This is the start of our third season with this insert and it is the same aggravating issue every year. First the pilot light won't stay lit then when it is lit the fire lights and then clicks off. If I use the manual remote setting and turn it off before it cancels and then restart it a number of times I can get the fire to stay lit then when I turn the fire off the pilot goes out as well. The flames are very blue and wispy to start often don't get better until I have a service call and the technician resets it. What do I need to do to jsut be able to turn the gas on and light the stove each season. After the tech comes and resets it the stove works flawlesly all winter.

when you light the pilot do you hold the knob down for 30-45 seconds? if not it isnt heating up the t-couple. that is what keeps the pilot light on.
