Ordered the spark module kit, replaced the spark module and resolved the problem. In my case (Maytag GS5770ADCM), installation was more difficult than normal and required removing burner top grates, burners, chrome pans, burner housings, entire top of range, top bottom pan, disconnecting 2 gas lines to right side burners, and modifing original module mounting bracket. Note that there are many screws that need to be removed and DIYers should mark/track each removal for ease of reinstall. Recommend that DIYers identify location of spark module and amount of work required before attelmpting repairs. Degree of difficulty in replacing spark module will vary depending on brand and model.
