Toyota Repair: 1994 toyota camry- ac stalls engine, hot days hard to start, toyota camry, minor inconvenience

Question
1994 toyota camry le 2.2 160k miles.
We live in minnesota and the car starts like a top in very cold to cool temps, but when it gets hot out, you have to try 2-4 times (5 sec each) before it starts. then it runs fine. This isn't right but it is only a minor inconvenience for now. It's been doing that for 3 years now. I just don't know if it may lead to worse problems. Our big problem is when we use the ac it blows nice and cold and seems to work just fine but you'll be cruising down the road and the engine will just die and then it won't turn over at all. If you wait for 20 minutes or so it will turn over and start. If you don't use the ac there's no problems (except for the hot start up deal i was talking about in the first place). Thanks for your input.

Answer
strange that the car dies with the ac on.
Maybe the compressor tightens up when hot?

AS far as the hot no start. You have the possibility of several problems.
could be fuel trim issue. Youll need to check for ECU codes and then look at the data list to tell if theres an issue. You look for fuel trim numbers higher than 10.
that would be helpful in the diag process.
