hi, i am brand new to this , i just bought an 88 ranger 2.9 auto .it will run fine ,and suddenly die and refuse to start.i have replaced tfi module on distributor , and wired inertia switch wires together.truck will run for up to as much as a couple days ,then dies and no start.last night it dawned on me that pulling the positive battery cable will cause it to start(i assume it resets the computer)but it still eventually dies and won't start,any help would be greatly appreciated. thank you-mark2259
