Where the boiler is providing a hot water feed to the shower and your finding water goes cold after 90 seconds but get a constant hot water for longer when leaving the hot tap running its more likely to be the thermostatic valve in the mixer tap of the shower than the boiler, the only potential cause I can see on the boiler is a lack of flow making it switch off as its not detecting demand.
