We are also facing funny timer isr behaviour. I have written TImer ISR to generate one_sec bit and toggle an LED. In main I dump a message on LCD display, and increment a step_number. when quantity of this step crosses 20 or so, timer stops working, LED stops toggling. We are using keil and LPC2132. I want to know what is exact problem you are fcing. Is it same as my problem?
