Here is your answer, TFI module.. they go flaky and bad quite often. also make sure you have a good engine ground. I went though 12 tfi's and 7 distributors till i found out my engine ground was corroded. yea, non winter car with 55K no rain either. common problem.. what i would do, get a ground cable, bolt it to the distributor hold down nut, then go to the battery get new stuff and BAM.. all set with better than before response. the stators in the distributor go bad due to the grounding and kill the TFI in the process. TFI's have a high side and low side to them. sounds like your high side is gone. sounds like alot but trust me its your issue.. let me know if you need more help.. Good luck!
