Why will my Pathfinder will not start when engine is warm/hot/

Question

Pathfinder 1997 had cold start problem. Diagnostic codes p0120 and p1705 indicate the Throttle Position Sensor needed to be replaced. Put new TP Sensor on and it starts right up when cold. Now it will not start when the engine is warm or hot until it cools completely.
The battery tested low so I got new battery. Still no warm/hot start.
Any idea what the problem is? No other codes came up on the diagnostic test.
