Replaceing only this item fixed my problem
with front panel removed Ignier would turn on, gas would light, ignitor went out as usual, but gas would shut off after a few minutes and not come back on.
Note gas dryers are supposed to light, heat up, igniter stop flame stop after it gets up to temp, shut off for a while then repeat the process, it would have saved a lot of time researching to have known that earlier.. Take front panel off screws off, take panel off holding the 2 round coils in place, unplug the one with 3 prongs and replace, tested dryer with the panel off and the door closed so there was no suction issue. put panel back on 5 minute fix if you knew what you were doing.
